File EasyInstall.txt

+Easy Install
+Easy Install is a python module (``easy_install``) bundled with ``setuptools``
+that lets you automatically download, build, install, and manage Python
+Please share your experiences with us! If you encounter difficulty installing
+a package, please contact us via the `distutils mailing list
+<>`_.  (Note: please DO NOT send
+private email directly to the author of setuptools; it will be discarded.  The
+mailing list is a searchable archive of previously-asked and answered
+questions; you should begin your research there before reporting something as a
+bug -- and then do so via list discussion first.)
+(Also, if you'd like to learn about how you can use ``setuptools`` to make your
+own packages work better with EasyInstall, or provide EasyInstall-like features
+without requiring your users to use EasyInstall directly, you'll probably want
+to check out the full `setuptools`_ documentation as well.)
+.. contents:: **Table of Contents**
+Using "Easy Install"
+.. _installation instructions:
+Installing "Easy Install"
+Please see the `setuptools PyPI page <>`_
+for download links and basic installation instructions for each of the
+supported platforms.
+You will need at least Python 2.3.5, or if you are on a 64-bit platform, Python
+2.4.  An ``easy_install`` script will be installed in the normal location for
+Python scripts on your platform.
+Note that the instructions on the setuptools PyPI page assume that you are
+are installling to Python's primary ``site-packages`` directory.  If this is
+not the case, you should consult the section below on `Custom Installation
+Locations`_ before installing.  (And, on Windows, you should not use the
+``.exe`` installer when installing to an alternate location.)
+Note that ``easy_install`` normally works by downloading files from the
+internet.  If you are behind an NTLM-based firewall that prevents Python
+programs from accessing the net directly, you may wish to first install and use
+the `APS proxy server <>`_, which lets you get past such
+firewalls in the same way that your web browser(s) do.
+(Alternately, if you do not wish easy_install to actually download anything, you
+can restrict it from doing so with the ``--allow-hosts`` option; see the
+sections on `restricting downloads with --allow-hosts`_ and `command-line
+options`_ for more details.)
+If EasyInstall/setuptools appears to install correctly, and you can run the
+``easy_install`` command but it fails with an ``ImportError``, the most likely
+cause is that you installed to a location other than ``site-packages``,
+without taking any of the steps described in the `Custom Installation
+Locations`_ section below.  Please see that section and follow the steps to
+make sure that your custom location will work correctly.  Then re-install.
+Similarly, if you can run ``easy_install``, and it appears to be installing
+packages, but then you can't import them, the most likely issue is that you
+installed EasyInstall correctly but are using it to install packages to a
+non-standard location that hasn't been properly prepared.  Again, see the
+section on `Custom Installation Locations`_ for more details.
+Windows Notes
+On Windows, an ``easy_install.exe`` launcher will also be installed, so that
+you can just type ``easy_install`` as long as it's on your ``PATH``.  If typing
+``easy_install`` at the command prompt doesn't work, check to make sure your
+``PATH`` includes the appropriate ``C:\\Python2X\\Scripts`` directory.  On
+most current versions of Windows, you can change the ``PATH`` by right-clicking
+"My Computer", choosing "Properties" and selecting the "Advanced" tab, then
+clicking the "Environment Variables" button.  ``PATH`` will be in the "System
+Variables" section, and you will need to exit and restart your command shell
+(, cmd.exe, bash, or other) for the change to take effect.  Be sure
+to add a ``;`` after the last item on ``PATH`` before adding the scripts
+directory to it.
+Note that instead of changing your ``PATH`` to include the Python scripts
+directory, you can also retarget the installation location for scripts so they
+go on a directory that's already on the ``PATH``.  For more information see the
+sections below on `Command-Line Options`_ and `Configuration Files`_.  You
+can pass command line options (such as ``--script-dir``) to ```` to
+control where ``easy_install.exe`` will be installed.
+Downloading and Installing a Package
+For basic use of ``easy_install``, you need only supply the filename or URL of
+a source distribution or .egg file (`Python Egg`__).
+**Example 1**. Install a package by name, searching PyPI for the latest
+version, and automatically downloading, building, and installing it::
+    easy_install SQLObject
+**Example 2**. Install or upgrade a package by name and version by finding
+links on a given "download page"::
+    easy_install -f SQLObject
+**Example 3**. Download a source distribution from a specified URL,
+automatically building and installing it::
+    easy_install
+**Example 4**. Install an already-downloaded .egg file::
+    easy_install /my_downloads/OtherPackage-3.2.1-py2.3.egg
+**Example 5**.  Upgrade an already-installed package to the latest version
+listed on PyPI::
+    easy_install --upgrade PyProtocols
+**Example 6**.  Install a source distribution that's already downloaded and
+extracted in the current directory (New in 0.5a9)::
+    easy_install .
+**Example 7**.  (New in 0.6a1) Find a source distribution or Subversion
+checkout URL for a package, and extract it or check it out to
+``~/projects/sqlobject`` (the name will always be in all-lowercase), where it
+can be examined or edited.  (The package will not be installed, but it can
+easily be installed with ``easy_install ~/projects/sqlobject``.  See `Editing
+and Viewing Source Packages`_ below for more info.)::
+    easy_install --editable --build-directory ~/projects SQLObject
+Easy Install accepts URLs, filenames, PyPI package names (i.e., ``distutils``
+"distribution" names), and package+version specifiers.  In each case, it will
+attempt to locate the latest available version that meets your criteria.
+When downloading or processing downloaded files, Easy Install recognizes
+distutils source distribution files with extensions of .tgz, .tar, .tar.gz,
+.tar.bz2, or .zip.  And of course it handles already-built .egg
+distributions as well as ``.win32.exe`` installers built using distutils.
+By default, packages are installed to the running Python installation's
+``site-packages`` directory, unless you provide the ``-d`` or ``--install-dir``
+option to specify an alternative directory, or specify an alternate location
+using distutils configuration files.  (See `Configuration Files`_, below.)
+By default, any scripts included with the package are installed to the running
+Python installation's standard script installation location.  However, if you
+specify an installation directory via the command line or a config file, then
+the default directory for installing scripts will be the same as the package
+installation directory, to ensure that the script will have access to the
+installed package.  You can override this using the ``-s`` or ``--script-dir``
+Installed packages are added to an ``easy-install.pth`` file in the install
+directory, so that Python will always use the most-recently-installed version
+of the package.  If you would like to be able to select which version to use at
+runtime, you should use the ``-m`` or ``--multi-version`` option.
+Upgrading a Package
+You don't need to do anything special to upgrade a package: just install the
+new version, either by requesting a specific version, e.g.::
+    easy_install "SomePackage==2.0"
+a version greater than the one you have now::
+    easy_install "SomePackage>2.0"
+using the upgrade flag, to find the latest available version on PyPI::
+    easy_install --upgrade SomePackage
+or by using a download page, direct download URL, or package filename::
+    easy_install -f ExamplePackage
+    easy_install
+    easy_install my_downloads/ExamplePackage-2.0.tgz
+If you're using ``-m`` or ``--multi-version`` , using the ``require()``
+function at runtime automatically selects the newest installed version of a
+package that meets your version criteria.  So, installing a newer version is
+the only step needed to upgrade such packages.
+If you're installing to a directory on PYTHONPATH, or a configured "site"
+directory (and not using ``-m``), installing a package automatically replaces
+any previous version in the ``easy-install.pth`` file, so that Python will
+import the most-recently installed version by default.  So, again, installing
+the newer version is the only upgrade step needed.
+If you haven't suppressed script installation (using ``--exclude-scripts`` or
+``-x``), then the upgraded version's scripts will be installed, and they will
+be automatically patched to ``require()`` the corresponding version of the
+package, so that you can use them even if they are installed in multi-version
+``easy_install`` never actually deletes packages (unless you're installing a
+package with the same name and version number as an existing package), so if
+you want to get rid of older versions of a package, please see `Uninstalling
+Packages`_, below.
+Changing the Active Version
+If you've upgraded a package, but need to revert to a previously-installed
+version, you can do so like this::
+    easy_install PackageName==1.2.3
+Where ``1.2.3`` is replaced by the exact version number you wish to switch to.
+If a package matching the requested name and version is not already installed
+in a directory on ``sys.path``, it will be located via PyPI and installed.
+If you'd like to switch to the latest installed version of ``PackageName``, you
+can do so like this::
+    easy_install PackageName
+This will activate the latest installed version.  (Note: if you have set any
+``find_links`` via distutils configuration files, those download pages will be
+checked for the latest available version of the package, and it will be
+downloaded and installed if it is newer than your current version.)
+Note that changing the active version of a package will install the newly
+active version's scripts, unless the ``--exclude-scripts`` or ``-x`` option is
+Uninstalling Packages
+If you have replaced a package with another version, then you can just delete
+the package(s) you don't need by deleting the PackageName-versioninfo.egg file
+or directory (found in the installation directory).
+If you want to delete the currently installed version of a package (or all
+versions of a package), you should first run::
+    easy_install -m PackageName
+This will ensure that Python doesn't continue to search for a package you're
+planning to remove. After you've done this, you can safely delete the .egg
+files or directories, along with any scripts you wish to remove.
+Managing Scripts
+Whenever you install, upgrade, or change versions of a package, EasyInstall
+automatically installs the scripts for the selected package version, unless
+you tell it not to with ``-x`` or ``--exclude-scripts``.  If any scripts in
+the script directory have the same name, they are overwritten.
+Thus, you do not normally need to manually delete scripts for older versions of
+a package, unless the newer version of the package does not include a script
+of the same name.  However, if you are completely uninstalling a package, you
+may wish to manually delete its scripts.
+EasyInstall's default behavior means that you can normally only run scripts
+from one version of a package at a time.  If you want to keep multiple versions
+of a script available, however, you can simply use the ``--multi-version`` or
+``-m`` option, and rename the scripts that EasyInstall creates.  This works
+because EasyInstall installs scripts as short code stubs that ``require()`` the
+matching version of the package the script came from, so renaming the script
+has no effect on what it executes.
+For example, suppose you want to use two versions of the ``rst2html`` tool
+provided by the `docutils <>`_ package.  You might
+first install one version::
+    easy_install -m docutils==0.3.9
+then rename the ```` to ``r2h_039``, and install another version::
+    easy_install -m docutils==0.3.10
+This will create another ```` script, this one using docutils
+version 0.3.10 instead of 0.3.9.  You now have two scripts, each using a
+different version of the package.  (Notice that we used ``-m`` for both
+installations, so that Python won't lock us out of using anything but the most
+recently-installed version of the package.)
+Tips & Techniques
+Multiple Python Versions
+As of version 0.6a11, EasyInstall installs itself under two names:
+``easy_install`` and ``easy_install-N.N``, where ``N.N`` is the Python version
+used to install it.  Thus, if you install EasyInstall for both Python 2.3 and
+2.4, you can use the ``easy_install-2.3`` or ``easy_install-2.4`` scripts to
+install packages for Python 2.3 or 2.4, respectively.
+Also, if you're working with Python version 2.4 or higher, you can run Python
+with ``-m easy_install`` to run that particular Python version's
+``easy_install`` command.
+Restricting Downloads with ``--allow-hosts``
+You can use the ``--allow-hosts`` (``-H``) option to restrict what domains
+EasyInstall will look for links and downloads on.  ``--allow-hosts=None``
+prevents downloading altogether.  You can also use wildcards, for example
+to restrict downloading to hosts in your own intranet.  See the section below
+on `Command-Line Options`_ for more details on the ``--allow-hosts`` option.
+By default, there are no host restrictions in effect, but you can change this
+default by editing the appropriate `configuration files`_ and adding::
+    [easy_install]
+    allow_hosts = *,*
+The above example would then allow downloads only from hosts in the
+```` and ```` domains, unless overridden on the
+command line.
+Installing on Un-networked Machines
+Just copy the eggs or source packages you need to a directory on the target
+machine, then use the ``-f`` or ``--find-links`` option to specify that
+directory's location.  For example::
+    easy_install -H None -f somedir SomePackage
+will attempt to install SomePackage using only eggs and source packages found
+in ``somedir`` and disallowing all remote access.  You should of course make
+sure you have all of SomePackage's dependencies available in somedir.
+If you have another machine of the same operating system and library versions
+(or if the packages aren't platform-specific), you can create the directory of
+eggs using a command like this::
+    easy_install -zmaxd somedir SomePackage
+This will tell EasyInstall to put zipped eggs or source packages for
+SomePackage and all its dependencies into ``somedir``, without creating any
+scripts or .pth files.  You can then copy the contents of ``somedir`` to the
+target machine.  (``-z`` means zipped eggs, ``-m`` means multi-version, which
+prevents .pth files from being used, ``-a`` means to copy all the eggs needed,
+even if they're installed elsewhere on the machine, and ``-d`` indicates the
+directory to place the eggs in.)
+You can also build the eggs from local development packages that were installed
+with the `` develop`` command, by including the ``-l`` option, e.g.::
+    easy_install -zmaxld somedir SomePackage
+This will use locally-available source distributions to build the eggs.
+Packaging Others' Projects As Eggs
+Need to distribute a package that isn't published in egg form?  You can use
+EasyInstall to build eggs for a project.  You'll want to use the ``--zip-ok``,
+``--exclude-scripts``, and possibly ``--no-deps`` options (``-z``, ``-x`` and
+``-N``, respectively).  Use ``-d`` or ``--install-dir`` to specify the location
+where you'd like the eggs placed.  By placing them in a directory that is
+published to the web, you can then make the eggs available for download, either
+in an intranet or to the internet at large.
+If someone distributes a package in the form of a single ``.py`` file, you can
+wrap it in an egg by tacking an ``#egg=name-version`` suffix on the file's URL.
+So, something like this::
+    easy_install -f "" foo
+will install the package as an egg, and this::
+    easy_install -zmaxd. \
+        -f "" foo
+will create a ``.egg`` file in the current directory.
+Creating your own Package Index
+In addition to local directories and the Python Package Index, EasyInstall can
+find download links on most any web page whose URL is given to the ``-f``
+(``--find-links``) option.  In the simplest case, you can simply have a web
+page with links to eggs or Python source packages, even an automatically
+generated directory listing (such as the Apache web server provides).
+If you are setting up an intranet site for package downloads, you may want to
+configure the target machines to use your download site by default, adding
+something like this to their `configuration files`_::
+    [easy_install]
+    find_links =
+As you can see, you can list multiple URLs separated by whitespace, continuing
+on multiple lines if necessary (as long as the subsequent lines are indented.
+If you are more ambitious, you can also create an entirely custom package index
+or PyPI mirror.  See the ``--index-url`` option under `Command-Line Options`_,
+below, and also the section on `Package Index "API"`_.
+Password-Protected Sites
+If a site you want to download from is password-protected using HTTP "Basic"
+authentication, you can specify your credentials in the URL, like so::
+You can do this with both index page URLs and direct download URLs.  As long
+as any HTML pages read by easy_install use *relative* links to point to the
+downloads, the same user ID and password will be used to do the downloading.
+Controlling Build Options
+EasyInstall respects standard distutils `Configuration Files`_, so you can use
+them to configure build options for packages that it installs from source.  For
+example, if you are on Windows using the MinGW compiler, you can configure the
+default compiler by putting something like this::
+    [build]
+    compiler = mingw32
+into the appropriate distutils configuration file.  In fact, since this is just
+normal distutils configuration, it will affect any builds using that config
+file, not just ones done by EasyInstall.  For example, if you add those lines
+to ``distutils.cfg`` in the ``distutils`` package directory, it will be the
+default compiler for *all* packages you build.  See `Configuration Files`_
+below for a list of the standard configuration file locations, and links to
+more documentation on using distutils configuration files.
+Editing and Viewing Source Packages
+Sometimes a package's source distribution  contains additional documentation,
+examples, configuration files, etc., that are not part of its actual code.  If
+you want to be able to examine these files, you can use the ``--editable``
+option to EasyInstall, and EasyInstall will look for a source distribution
+or Subversion URL for the package, then download and extract it or check it out
+as a subdirectory of the ``--build-directory`` you specify.  If you then wish
+to install the package after editing or configuring it, you can do so by
+rerunning EasyInstall with that directory as the target.
+Note that using ``--editable`` stops EasyInstall from actually building or
+installing the package; it just finds, obtains, and possibly unpacks it for
+you.  This allows you to make changes to the package if necessary, and to
+either install it in development mode using `` develop`` (if the
+package uses setuptools, that is), or by running ``easy_install projectdir``
+(where ``projectdir`` is the subdirectory EasyInstall created for the
+downloaded package.
+In order to use ``--editable`` (``-e`` for short), you *must* also supply a
+``--build-directory`` (``-b`` for short).  The project will be placed in a
+subdirectory of the build directory.  The subdirectory will have the same
+name as the project itself, but in all-lowercase.  If a file or directory of
+that name already exists, EasyInstall will print an error message and exit.
+Also, when using ``--editable``, you cannot use URLs or filenames as arguments.
+You *must* specify project names (and optional version requirements) so that
+EasyInstall knows what directory name(s) to create.  If you need to force
+EasyInstall to use a particular URL or filename, you should specify it as a
+``--find-links`` item (``-f`` for short), and then also specify
+the project name, e.g.::
+    easy_install -eb ~/projects \
+     -f \
+     ctypes==0.9.6
+Dealing with Installation Conflicts
+(NOTE: As of 0.6a11, this section is obsolete; it is retained here only so that
+people using older versions of EasyInstall can consult it.  As of version
+0.6a11, installation conflicts are handled automatically without deleting the
+old or system-installed packages, and without ignoring the issue.  Instead,
+eggs are automatically shifted to the front of ``sys.path`` using special
+code added to the ``easy-install.pth`` file.  So, if you are using version
+0.6a11 or better of setuptools, you do not need to worry about conflicts,
+and the following issues do not apply to you.)
+EasyInstall installs distributions in a "managed" way, such that each
+distribution can be independently activated or deactivated on ``sys.path``.
+However, packages that were not installed by EasyInstall are "unmanaged",
+in that they usually live all in one directory and cannot be independently
+activated or deactivated.
+As a result, if you are using EasyInstall to upgrade an existing package, or
+to install a package with the same name as an existing package, EasyInstall
+will warn you of the conflict.  (This is an improvement over ``
+install``, becuase the ``distutils`` just install new packages on top of old
+ones, possibly combining two unrelated packages or leaving behind modules that
+have been deleted in the newer version of the package.)
+By default, EasyInstall will stop the installation if it detects a conflict
+between an existing, "unmanaged" package, and a module or package in any of
+the distributions you're installing.  It will display a list of all of the
+existing files and directories that would need to be deleted for the new
+package to be able to function correctly.  You can then either delete these
+conflicting files and directories yourself and re-run EasyInstall, or you can
+just use the ``--delete-conflicting`` or ``--ignore-conflicts-at-my-risk``
+options, as described under `Command-Line Options`_, below.
+Of course, once you've replaced all of your existing "unmanaged" packages with
+versions managed by EasyInstall, you won't have any more conflicts to worry
+Compressed Installation
+EasyInstall tries to install packages in zipped form, if it can.  Zipping
+packages can improve Python's overall import performance if you're not using
+the ``--multi-version`` option, because Python processes zipfile entries on
+``sys.path`` much faster than it does directories.
+As of version 0.5a9, EasyInstall analyzes packages to determine whether they
+can be safely installed as a zipfile, and then acts on its analysis.  (Previous
+versions would not install a package as a zipfile unless you used the
+``--zip-ok`` option.)
+The current analysis approach is fairly conservative; it currenly looks for:
+ * Any use of the ``__file__`` or ``__path__`` variables (which should be
+   replaced with ``pkg_resources`` API calls)
+ * Possible use of ``inspect`` functions that expect to manipulate source files
+   (e.g. ``inspect.getsource()``)
+ * Top-level modules that might be scripts used with ``python -m`` (Python 2.4)
+If any of the above are found in the package being installed, EasyInstall will
+assume that the package cannot be safely run from a zipfile, and unzip it to
+a directory instead.  You can override this analysis with the ``-zip-ok`` flag,
+which will tell EasyInstall to install the package as a zipfile anyway.  Or,
+you can use the ``--always-unzip`` flag, in which case EasyInstall will always
+unzip, even if its analysis says the package is safe to run as a zipfile.
+Normally, however, it is simplest to let EasyInstall handle the determination
+of whether to zip or unzip, and only specify overrides when needed to work
+around a problem.  If you find you need to override EasyInstall's guesses, you
+may want to contact the package author and the EasyInstall maintainers, so that
+they can make appropriate changes in future versions.
+(Note: If a package uses ``setuptools`` in its setup script, the package author
+has the option to declare the package safe or unsafe for zipped usage via the
+``zip_safe`` argument to ``setup()``.  If the package author makes such a
+declaration, EasyInstall believes the package's author and does not perform its
+own analysis.  However, your command-line option, if any, will still override
+the package author's choice.)
+Reference Manual
+Configuration Files
+(New in 0.4a2)
+You may specify default options for EasyInstall using the standard
+distutils configuration files, under the command heading ``easy_install``.
+EasyInstall will look first for a ``setup.cfg`` file in the current directory,
+then a ``~/.pydistutils.cfg`` or ``$HOME\\pydistutils.cfg`` (on Unix-like OSes
+and Windows, respectively), and finally a ``distutils.cfg`` file in the
+``distutils`` package directory.  Here's a simple example::
+    [easy_install]
+    # set the default location to install packages
+    install_dir = /home/me/lib/python
+    # Notice that indentation can be used to continue an option
+    # value; this is especially useful for the "--find-links"
+    # option, which tells easy_install to use download links on
+    # these pages before consulting PyPI:
+    #
+    find_links =
+In addition to accepting configuration for its own options under
+``[easy_install]``, EasyInstall also respects defaults specified for other
+distutils commands.  For example, if you don't set an ``install_dir`` for
+``[easy_install]``, but *have* set an ``install_lib`` for the ``[install]``
+command, this will become EasyInstall's default installation directory.  Thus,
+if you are already using distutils configuration files to set default install
+locations, build options, etc., EasyInstall will respect your existing settings
+until and unless you override them explicitly in an ``[easy_install]`` section.
+For more information, see also the current Python documentation on the `use and
+location of distutils configuration files <>`_.
+Command-Line Options
+``--zip-ok, -z``
+    Install all packages as zip files, even if they are marked as unsafe for
+    running as a zipfile.  This can be useful when EasyInstall's analysis
+    of a non-setuptools package is too conservative, but keep in mind that
+    the package may not work correctly.  (Changed in 0.5a9; previously this
+    option was required in order for zipped installation to happen at all.)
+``--always-unzip, -Z``
+    Don't install any packages as zip files, even if the packages are marked
+    as safe for running as a zipfile.  This can be useful if a package does
+    something unsafe, but not in a way that EasyInstall can easily detect.
+    EasyInstall's default analysis is currently very conservative, however, so
+    you should only use this option if you've had problems with a particular
+    package, and *after* reporting the problem to the package's maintainer and
+    to the EasyInstall maintainers.
+    (Note: the ``-z/-Z`` options only affect the installation of newly-built
+    or downloaded packages that are not already installed in the target
+    directory; if you want to convert an existing installed version from
+    zipped to unzipped or vice versa, you'll need to delete the existing
+    version first, and re-run EasyInstall.)
+``--multi-version, -m``
+    "Multi-version" mode. Specifying this option prevents ``easy_install`` from
+    adding an ``easy-install.pth`` entry for the package being installed, and
+    if an entry for any version the package already exists, it will be removed
+    upon successful installation. In multi-version mode, no specific version of
+    the package is available for importing, unless you use
+    ``pkg_resources.require()`` to put it on ``sys.path``. This can be as
+    simple as::
+        from pkg_resources import require
+        require("SomePackage", "OtherPackage", "MyPackage")
+    which will put the latest installed version of the specified packages on
+    ``sys.path`` for you. (For more advanced uses, like selecting specific
+    versions and enabling optional dependencies, see the ``pkg_resources`` API
+    doc.)
+    Changed in 0.6a10: this option is no longer silently enabled when
+    installing to a non-PYTHONPATH, non-"site" directory.  You must always
+    explicitly use this option if you want it to be active.
+``--upgrade, -U``   (New in 0.5a4)
+    By default, EasyInstall only searches online if a project/version
+    requirement can't be met by distributions already installed
+    on sys.path or the installation directory.  However, if you supply the
+    ``--upgrade`` or ``-U`` flag, EasyInstall will always check the package
+    index and ``--find-links`` URLs before selecting a version to install.  In
+    this way, you can force EasyInstall to use the latest available version of
+    any package it installs (subject to any version requirements that might
+    exclude such later versions).
+``--install-dir=DIR, -d DIR``
+    Set the installation directory. It is up to you to ensure that this
+    directory is on ``sys.path`` at runtime, and to use
+    ``pkg_resources.require()`` to enable the installed package(s) that you
+    need.
+    (New in 0.4a2) If this option is not directly specified on the command line
+    or in a distutils configuration file, the distutils default installation
+    location is used.  Normally, this would be the ``site-packages`` directory,
+    but if you are using distutils configuration files, setting things like
+    ``prefix`` or ``install_lib``, then those settings are taken into
+    account when computing the default installation directory, as is the
+    ``--prefix`` option.
+``--script-dir=DIR, -s DIR``
+    Set the script installation directory.  If you don't supply this option
+    (via the command line or a configuration file), but you *have* supplied
+    an ``--install-dir`` (via command line or config file), then this option
+    defaults to the same directory, so that the scripts will be able to find
+    their associated package installation.  Otherwise, this setting defaults
+    to the location where the distutils would normally install scripts, taking
+    any distutils configuration file settings into account.
+``--exclude-scripts, -x``
+    Don't install scripts.  This is useful if you need to install multiple
+    versions of a package, but do not want to reset the version that will be
+    run by scripts that are already installed.
+``--always-copy, -a``   (New in 0.5a4)
+    Copy all needed distributions to the installation directory, even if they
+    are already present in a directory on sys.path.  In older versions of
+    EasyInstall, this was the default behavior, but now you must explicitly
+    request it.  By default, EasyInstall will no longer copy such distributions
+    from other sys.path directories to the installation directory, unless you
+    explicitly gave the distribution's filename on the command line.
+    Note that as of 0.6a10, using this option excludes "system" and
+    "development" eggs from consideration because they can't be reliably
+    copied.  This may cause EasyInstall to choose an older version of a package
+    than what you expected, or it may cause downloading and installation of a
+    fresh copy of something that's already installed.  You will see warning
+    messages for any eggs that EasyInstall skips, before it falls back to an
+    older version or attempts to download a fresh copy.
+    Scan the specified "download pages" or directories for direct links to eggs
+    or other distributions.  Any existing file or directory names or direct
+    download URLs are immediately added to EasyInstall's search cache, and any
+    indirect URLs (ones that don't point to eggs or other recognized archive
+    formats) are added to a list of additional places to search for download
+    links.  As soon as EasyInstall has to go online to find a package (either
+    because it doesn't exist locally, or because ``--upgrade`` or ``-U`` was
+    used), the specified URLs will be downloaded and scanned for additional
+    direct links.
+    Eggs and archives found by way of ``--find-links`` are only downloaded if
+    they are needed to meet a requirement specified on the command line; links
+    to unneeded packages are ignored.
+    If all requested packages can be found using links on the specified
+    download pages, the Python Package Index will not be consulted unless you
+    also specified the ``--upgrade`` or ``-U`` option.
+    (Note: if you want to refer to a local HTML file containing links, you must
+    use a ``file:`` URL, as filenames that do not refer to a directory, egg, or
+    archive are ignored.)
+    You may specify multiple URLs or file/directory names with this option,
+    separated by whitespace.  Note that on the command line, you will probably
+    have to surround the URL list with quotes, so that it is recognized as a
+    single option value.  You can also specify URLs in a configuration file;
+    see `Configuration Files`_, above.
+    Changed in 0.6a10: previously all URLs and directories passed to this
+    option were scanned as early as possible, but from 0.6a10 on, only
+    directories and direct archive links are scanned immediately; URLs are not
+    retrieved unless a package search was already going to go online due to a
+    package not being available locally, or due to the use of the ``--update``
+    or ``-U`` option.
+``--delete-conflicting, -D`` (Removed in 0.6a11)
+    (As of 0.6a11, this option is no longer necessary; please do not use it!)
+    If you are replacing a package that was previously installed *without*
+    using EasyInstall, the old version may end up on ``sys.path`` before the
+    version being installed with EasyInstall.  EasyInstall will normally abort
+    the installation of a package if it detects such a conflict, and ask you to
+    manually remove the conflicting files or directories.  If you specify this
+    option, however, EasyInstall will attempt to delete the files or
+    directories itself, and then proceed with the installation.
+``--ignore-conflicts-at-my-risk`` (Removed in 0.6a11)
+    (As of 0.6a11, this option is no longer necessary; please do not use it!)
+    Ignore conflicting packages and proceed with installation anyway, even
+    though it means the package probably won't work properly.  If the
+    conflicting package is in a directory you can't write to, this may be your
+    only option, but you will need to take more invasive measures to get the
+    installed package to work, like manually adding it to ``PYTHONPATH`` or to
+    ``sys.path`` at runtime.
+``--index-url=URL, -i URL`` (New in 0.4a1; default changed in 0.6c7)
+    Specifies the base URL of the Python Package Index.  The default is
+ if not specified.  When a package is requested
+    that is not locally available or linked from a ``--find-links`` download
+    page, the package index will be searched for download pages for the needed
+    package, and those download pages will be searched for links to download
+    an egg or source distribution.
+``--editable, -e`` (New in 0.6a1)
+    Only find and download source distributions for the specified projects,
+    unpacking them to subdirectories of the specified ``--build-directory``.
+    EasyInstall will not actually build or install the requested projects or
+    their dependencies; it will just find and extract them for you.  See
+    `Editing and Viewing Source Packages`_ above for more details.
+``--build-directory=DIR, -b DIR`` (UPDATED in 0.6a1)
+    Set the directory used to build source packages.  If a package is built
+    from a source distribution or checkout, it will be extracted to a
+    subdirectory of the specified directory.  The subdirectory will have the
+    same name as the extracted distribution's project, but in all-lowercase.
+    If a file or directory of that name already exists in the given directory,
+    a warning will be printed to the console, and the build will take place in
+    a temporary directory instead.
+    This option is most useful in combination with the ``--editable`` option,
+    which forces EasyInstall to *only* find and extract (but not build and
+    install) source distributions.  See `Editing and Viewing Source Packages`_,
+    above, for more information.
+``--verbose, -v, --quiet, -q`` (New in 0.4a4)
+    Control the level of detail of EasyInstall's progress messages.  The
+    default detail level is "info", which prints information only about
+    relatively time-consuming operations like running a setup script, unpacking
+    an archive, or retrieving a URL.  Using ``-q`` or ``--quiet`` drops the
+    detail level to "warn", which will only display installation reports,
+    warnings, and errors.  Using ``-v`` or ``--verbose`` increases the detail
+    level to include individual file-level operations, link analysis messages,
+    and distutils messages from any setup scripts that get run.  If you include
+    the ``-v`` option more than once, the second and subsequent uses are passed
+    down to any setup scripts, increasing the verbosity of their reporting as
+    well.
+``--dry-run, -n`` (New in 0.4a4)
+    Don't actually install the package or scripts.  This option is passed down
+    to any setup scripts run, so packages should not actually build either.
+    This does *not* skip downloading, nor does it skip extracting source
+    distributions to a temporary/build directory.
+``--optimize=LEVEL``, ``-O LEVEL`` (New in 0.4a4)
+    If you are installing from a source distribution, and are *not* using the
+    ``--zip-ok`` option, this option controls the optimization level for
+    compiling installed ``.py`` files to ``.pyo`` files.  It does not affect
+    the compilation of modules contained in ``.egg`` files, only those in
+    ``.egg`` directories.  The optimization level can be set to 0, 1, or 2;
+    the default is 0 (unless it's set under ``install`` or ``install_lib`` in
+    one of your distutils configuration files).
+``--record=FILENAME``  (New in 0.5a4)
+    Write a record of all installed files to FILENAME.  This is basically the
+    same as the same option for the standard distutils "install" command, and
+    is included for compatibility with tools that expect to pass this option
+    to " install".
+``--site-dirs=DIRLIST, -S DIRLIST``   (New in 0.6a1)
+    Specify one or more custom "site" directories (separated by commas).
+    "Site" directories are directories where ``.pth`` files are processed, such
+    as the main Python ``site-packages`` directory.  As of 0.6a10, EasyInstall
+    automatically detects whether a given directory processes ``.pth`` files
+    (or can be made to do so), so you should not normally need to use this
+    option.  It is is now only necessary if you want to override EasyInstall's
+    judgment and force an installation directory to be treated as if it
+    supported ``.pth`` files.
+    (If you want to *make* a non-``PYTHONPATH`` directory support ``.pth``
+    files, please see the `Administrator Installation`_ section below.)
+``--no-deps, -N``  (New in 0.6a6)
+    Don't install any dependencies.  This is intended as a convenience for
+    tools that wrap eggs in a platform-specific packaging system.  (We don't
+    recommend that you use it for anything else.)
+``--allow-hosts=PATTERNS, -H PATTERNS``   (New in 0.6a6)
+    Restrict downloading and spidering to hosts matching the specified glob
+    patterns.  E.g. ``-H *`` restricts web access so that only
+    packages listed and downloadable from machines in the ````
+    domain.  The glob patterns must match the *entire* user/host/port section of
+    the target URL(s).  For example, ``*`` will NOT accept a URL
+    like ```` or ````.
+    Multiple patterns can be specified by separting them with commas.  The
+    default pattern is ``*``, which matches anything.
+    In general, this option is mainly useful for blocking EasyInstall's web
+    access altogether (e.g. ``-Hlocalhost``), or to restrict it to an intranet
+    or other trusted site.  EasyInstall will do the best it can to satisfy
+    dependencies given your host restrictions, but of course can fail if it
+    can't find suitable packages.  EasyInstall displays all blocked URLs, so
+    that you can adjust your ``--allow-hosts`` setting if it is more strict
+    than you intended.  Some sites may wish to define a restrictive default
+    setting for this option in their `configuration files`_, and then manually
+    override the setting on the command line as needed.
+``--prefix=DIR`` (New in 0.6a10)
+    Use the specified directory as a base for computing the default
+    installation and script directories.  On Windows, the resulting default
+    directories will be ``prefix\\Lib\\site-packages`` and ``prefix\\Scripts``,
+    while on other platforms the defaults will be
+    ``prefix/lib/python2.X/site-packages`` (with the appropriate version
+    substituted) for libraries and ``prefix/bin`` for scripts.
+    Note that the ``--prefix`` option only sets the *default* installation and
+    script directories, and does not override the ones set on the command line
+    or in a configuration file.
+``--local-snapshots-ok, -l`` (New in 0.6c6)
+    Normally, EasyInstall prefers to only install *released* versions of
+    projects, not in-development ones, because such projects may not
+    have a currently-valid version number.  So, it usually only installs them
+    when their ```` directory is explicitly passed on the command line.
+    However, if this option is used, then any in-development projects that were
+    installed using the `` develop`` command, will be used to build
+    eggs, effectively upgrading the "in-development" project to a snapshot
+    release.  Normally, this option is used only in conjunction with the
+    ``--always-copy`` option to create a distributable snapshot of every egg
+    needed to run an application.
+    Note that if you use this option, you must make sure that there is a valid
+    version number (such as an SVN revision number tag) for any in-development
+    projects that may be used, as otherwise EasyInstall may not be able to tell
+    what version of the project is "newer" when future installations or
+    upgrades are attempted.
+.. _non-root installation:
+Custom Installation Locations
+EasyInstall manages what packages are active using Python ``.pth`` files, which
+are normally only usable in Python's main ``site-packages`` directory.  On some
+platforms (such as Mac OS X), there are additional ``site-packages``
+directories that you can use besides the main one, but usually there is only
+one directory on the system where you can install packages without extra steps.
+There are many reasons, however, why you might want to install packages
+somewhere other than the ``site-packages`` directory.  For example, you might
+not have write access to that directory.  You may be working with unstable
+versions of packages that you don't want to install system-wide.  And so on.
+The following sections describe various approaches to custom installation; feel
+free to choose which one best suits your system and needs.
+`Administrator Installation`_
+    This approach is for when you have write access to ``site-packages`` (or
+    another directory where ``.pth`` files are processed), but don't want to
+    install packages there.  This can also be used by a system administrator
+    to enable each user having their own private directories that EasyInstall
+    will use to install packages.
+`Mac OS X "User" Installation`_
+    This approach produces a result similar to an administrator installation
+    that gives each user their own private package directory, but on Mac OS X
+    the hard part has already been done for you.  This is probably the best
+    approach for Mac OS X users.
+`Creating a "Virtual" Python`_
+    This approach is for when you don't have "root" or access to write to the
+    ``site-packages`` directory, and would like to be able to set up one or
+    more "virtual python" executables for your projects.  This approach
+    gives you the benefits of multiple Python installations, but without having
+    to actually install Python more than once and use up lots of disk space.
+    (Only the Python executable is copied; the libraries will be symlinked
+    from the systemwide Python.)
+    If you don't already have any ``PYTHONPATH`` customization or
+    special distutils configuration, and you can't use either of the preceding
+    approaches, this is probably the best one for you.
+`"Traditional" PYTHONPATH-based Installation`_
+    If you already have a custom ``PYTHONPATH``, and/or a custom distutils
+    configuration, and don't want to change any of your existing setup, you may
+    be interested in this approach.  (If you're using a custom ``.pth`` file to
+    point to your custom installation location, however, you should use
+    `Administrator Installation`_ to enable ``.pth`` processing in the custom
+    location instead, as that is easier and more flexible than this approach.)
+Administrator Installation
+If you have root access to your machine, you can easily configure it to allow
+each user to have their own directory where Python packages can be installed
+and managed by EasyInstall.
+First, create an ``altinstall.pth`` file in Python's ``site-packages``
+directory,  containing the following line (substituting the correct Python
+    import os, site; site.addsitedir(os.path.expanduser('~/lib/python2.3'))
+This will automatically add each user's ``~/lib/python2.X`` directory to
+``sys.path`` (if it exists), *and* it will process any ``.pth`` files in that
+directory -- which is what makes it usable with EasyInstall.
+The next step is to create or modify ``distutils.cfg`` in the ``distutils``
+directory of your Python library.  The correct directory will be something like
+``/usr/lib/python2.X/distutils`` on most Posix systems and something like
+``C:\\Python2X\Lib\distutils`` on Windows machines.  Add the following lines
+to the file, substituting the correct Python version if necessary::
+    [install]
+    install_lib = ~/lib/python2.3
+    # This next line is optional but often quite useful; it directs EasyInstall
+    # and the distutils to install scripts in the user's "bin" directory.  For
+    # Mac OS X framework Python builds, you should use /usr/local/bin instead,
+    # because neither ~/bin nor the default script installation location are on
+    # the system PATH.
+    #
+    install_scripts = ~/bin
+This will configure the distutils and EasyInstall to install packages to the
+user's home directory by default.
+Of course, you aren't limited to using a ``~/lib/python2.X`` directory with
+this approach.  You can substitute a specific systemwide directory if you like.
+You can also edit ``~/.pydistutils.cfg`` (or ``~/pydistutils.cfg`` on Windows)
+instead of changing the master ``distutils.cfg`` file.  The true keys of this
+approach are simply that:
+1. any custom installation directory must be added to ``sys.path`` using a
+   ``site.addsitedir()`` call from a working ``.pth`` file or
+   ````.
+2. The active distutils configuration file(s) or ``easy_install`` command line
+   should include the custom directory in the ``--site-dirs`` option, so that
+   EasyInstall knows that ``.pth`` files will work in that location.  (This is
+   because Python does not keep track of what directories are or aren't enabled
+   for ``.pth`` processing, in any way that EasyInstall can find out.)
+As long as both of these things have been done, your custom installation
+location is good to go.
+Mac OS X "User" Installation
+If you are on a Mac OS X machine, you should just use the
+``~/Library/Python/2.x/site-packages`` directory as your custom installation
+location, because it is already configured to process ``.pth`` files, and
+EasyInstall already knows this.
+Before installing EasyInstall/setuptools, just create a ``~/.pydistutils.cfg``
+file with the following contents (or add this to the existing contents)::
+    [install]
+    install_lib = ~/Library/Python/$py_version_short/site-packages
+    install_scripts = ~/bin
+This will tell the distutils and EasyInstall to always install packages in
+your personal ``site-packages`` directory, and scripts to ``~/bin``.  (Note: do
+*not* replace ``$py_version_short`` with an actual Python version in the
+configuration file!  The distutils will substitute the correct value at
+runtime, so that the above configuration file should work correctly no matter
+what Python version you use, now or in the future.)
+Once you have done this, you can follow the normal `installation instructions`_
+and use ``easy_install`` without any other special options or steps.
+(Note, however, that ``~/bin`` is not in the default ``PATH``, so you may have
+to refer to scripts by their full location.  You may want to modify your shell
+startup script (likely ``.bashrc`` or ``.profile``) or your
+``~/.MacOSX/environment.plist`` to include ``~/bin`` in your ``PATH``.
+Creating a "Virtual" Python
+If you are on a Linux, BSD, Cygwin, or other similar Unix-like operating
+system, but don't have root access, you can create your own "virtual"
+Python installation, which uses its own library directories and some symlinks
+to the site-wide Python.
+In the simplest case, your virtual Python installation will live under the
+``~/lib/python2.x``, ``~/include/python2.x``, and ``~/bin`` directories.  Just
+download ``_ and run it using the site-wide Python.  If you
+want to customize the location, you can use the ``--prefix`` option to specify
+an installation base directory in place of ``~``.  (Use ``--help`` to get the
+complete list of options.)
+When you're done, you'll have a ``~/bin/python`` executable that's linked to
+the local Python installation and inherits all its current libraries, but which
+allows you to add as many new libraries as you want.  Simply use this new
+Python in place of your system-defined one, and you can modify it as you like
+without breaking anything that relies on the system Python.  You'll also still
+need to follow the standard `installation instructions`_ to install setuptools
+and EasyInstall, using your new ``~/bin/python`` executable in place of the
+system Python.
+Note that if you were previously setting a ``PYTHONPATH`` and/or had other
+special configuration options in your ``~/.pydistutils.cfg``, you may need to
+remove these settings *before* running ````.  This is because
+your new Python executable will not need *any* custom configuration for the
+distutils or EasyInstall; everything will go to the correct ``~/lib`` and
+``~/bin`` directories automatically.
+You should, however, also make sure that the ``bin`` subdirectory of your
+installation prefix (e.g. ``~/bin``) is on your ``PATH``, because that is where
+EasyInstall and the distutils will install new Python scripts.
+"Traditional" ``PYTHONPATH``-based Installation
+This installation method is not as robust or as flexible as `creating a
+"virtual" python`_ installation, as it uses various tricks to fool Python into
+processing ``.pth`` files where it normally wouldn't.  We suggest you at least
+consider using one of the other approaches, as they will generally result in
+a cleaner, more usable Python configuration.  However, if for some reason you
+can't or won't use one of the other approaches, here's how to do it.
+Assuming that you want to install packages in a directory called ``~/py-lib``,
+and scripts in ``~/bin``, here's what you need to do:
+First, edit ``~/.pydistutils.cfg`` to include these settings, if you don't
+already have them::
+    [install]
+    install_lib = ~/py-lib
+    install_scripts = ~/bin
+Be sure to do this *before* you try to run the ```` installation
+script.  Then, follow the standard `installation instructions`_, but make
+sure that ``~/py-lib`` is listed in your ``PYTHONPATH`` environment variable.
+Your library installation directory *must* be in listed in ``PYTHONPATH``,
+not only when you install packages with EasyInstall, but also when you use
+any packages that are installed using EasyInstall.  You will probably want to
+edit your ``~/.profile`` or other configuration file(s) to ensure that it is
+set, if you haven't already got this set up on your machine.
+Package Index "API"
+Custom package indexes (and PyPI) must follow the following rules for
+EasyInstall to be able to look up and download packages:
+1. Except where stated otherwise, "pages" are HTML or XHTML, and "links"
+   refer to ``href`` attributes.
+2. Individual project version pages' URLs must be of the form
+   ``base/projectname/version``, where ``base`` is the package index's base URL.
+3. Omitting the ``/version`` part of a project page's URL (but keeping the
+   trailing ``/``) should result in a page that is either:
+   a) The single active version of that project, as though the version had been
+      explicitly included, OR
+   b) A page with links to all of the active version pages for that project.
+4. Individual project version pages should contain direct links to downloadable
+   distributions where possible.  It is explicitly permitted for a project's
+   "long_description" to include URLs, and these should be formatted as HTML
+   links by the package index, as EasyInstall does no special processing to
+   identify what parts of a page are index-specific and which are part of the
+   project's supplied description.
+5. Where available, MD5 information should be added to download URLs by
+   appending a fragment identifier of the form ``#md5=...``, where ``...`` is
+   the 32-character hex MD5 digest.  EasyInstall will verify that the
+   downloaded file's MD5 digest matches the given value.
+6. Individual project version pages should identify any "homepage" or
+   "download" URLs using ``rel="homepage"`` and ``rel="download"`` attributes
+   on the HTML elements linking to those URLs. Use of these attributes will
+   cause EasyInstall to always follow the provided links, unless it can be
+   determined by inspection that they are downloadable distributions. If the
+   links are not to downloadable distributions, they are retrieved, and if they
+   are HTML, they are scanned for download links. They are *not* scanned for
+   additional "homepage" or "download" links, as these are only processed for
+   pages that are part of a package index site.
+7. The root URL of the index, if retrieved with a trailing ``/``, must result
+   in a page containing links to *all* projects' active version pages.
+   (Note: This requirement is a workaround for the absence of case-insensitive
+   ``safe_name()`` matching of project names in URL paths. If project names are
+   matched in this fashion (e.g. via the PyPI server, mod_rewrite, or a similar
+   mechanism), then it is not necessary to include this all-packages listing
+   page.)
+8. If a package index is accessed via a ``file://`` URL, then EasyInstall will
+   automatically use ``index.html`` files, if present, when trying to read a
+   directory with a trailing ``/`` on the URL.
+Backward Compatibility
+Package indexes that wish to support setuptools versions prior to 0.6b4 should
+also follow these rules:
+* Homepage and download links must be preceded with ``"<th>Home Page"`` or
+  ``"<th>Download URL"``, in addition to (or instead of) the ``rel=""``
+  attributes on the actual links.  These marker strings do not need to be
+  visible, or uncommented, however!  For example, the following is a valid
+  homepage link that will work with any version of setuptools::
+    <li>
+     <strong>Home Page:</strong>
+     <!-- <th>Home Page -->
+     <a rel="homepage" href=""></a>
+    </li>
+  Even though the marker string is in an HTML comment, older versions of
+  EasyInstall will still "see" it and know that the link that follows is the
+  project's home page URL.
+* The pages described by paragraph 3(b) of the preceding section *must*
+  contain the string ``"Index of Packages</title>"`` somewhere in their text.
+  This can be inside of an HTML comment, if desired, and it can be anywhere
+  in the page.  (Note: this string MUST NOT appear on normal project pages, as
+  described in paragraphs 2 and 3(a)!)
+In addition, for compatibility with PyPI versions that do not use ``#md5=``
+fragment IDs, EasyInstall uses the following regular expression to match PyPI's
+displayed MD5 info (broken onto two lines for readability)::
+    <a href="([^"#]+)">([^<]+)</a>\n\s+\(<a href="[^?]+\?:action=show_md5
+    &amp;digest=([0-9a-f]{32})">md5</a>\)
+ * Fixed ``win32.exe`` support for .pth files, so unnecessary directory nesting
+   is flattened out in the resulting egg.  (There was a case-sensitivity
+   problem that affected some distributions, notably ``pywin32``.)
+ * Prevent ``--help-commands`` and other junk from showing under Python 2.5
+   when running ``easy_install --help``.
+ * Fixed GUI scripts sometimes not executing on Windows
+ * Fixed not picking up dependency links from recursive dependencies.
+ * Only make ``.py``, ``.dll`` and ``.so`` files executable when unpacking eggs
+ * Changes for Jython compatibility
+ * Improved error message when a requirement is also a directory name, but the
+   specified directory is not a source package.
+ * Fixed ``--allow-hosts`` option blocking ``file:`` URLs
+ * Fixed HTTP SVN detection failing when the page title included a project
+   name (e.g. on SourceForge-hosted SVN)
+ * Fix Jython script installation to handle ``#!`` lines better when
+   ``sys.executable`` is a script.
+ * Removed use of deprecated ``md5`` module if ``hashlib`` is available
+ * Keep site directories (e.g. ``site-packages``) from being included in
+   ``.pth`` files.
+ * ``ftp:`` download URLs now work correctly.
+ * The default ``--index-url`` is now ````, to use
+   the Python Package Index's new simpler (and faster!) REST API.
+ * EasyInstall no longer aborts the installation process if a URL it wants to
+   retrieve can't be downloaded, unless the URL is an actual package download.
+   Instead, it issues a warning and tries to keep going.
+ * Fixed distutils-style scripts originally built on Windows having their line
+   endings doubled when installed on any platform.
+ * Added ``--local-snapshots-ok`` flag, to allow building eggs from projects
+   installed using `` develop``.
+ * Fixed not HTML-decoding URLs scraped from web pages
+ * Fixed ``.dll`` files on Cygwin not having executable permisions when an egg
+   is installed unzipped.
+ * Added support for HTTP "Basic" authentication using ``http://user:pass@host``
+   URLs.  If a password-protected page contains links to the same host (and
+   protocol), those links will inherit the credentials used to access the
+   original page.
+ * Removed all special support for Sourceforge mirrors, as Sourceforge's
+   mirror system now works well for non-browser downloads.
+ * Fixed not recognizing ``win32.exe`` installers that included a custom
+   bitmap.
+ * Fixed not allowing ```` of paths outside the sandbox, even if they
+   are opened read-only (e.g. reading ``/dev/urandom`` for random numbers, as
+   is done by ``os.urandom()`` on some platforms).
+ * Fixed a problem with ``.pth`` testing on Windows when ``sys.executable``
+   has a space in it (e.g., the user installed Python to a ``Program Files``
+   directory).
+ * You can once again use "python -m easy_install" with Python 2.4 and above.
+ * Python 2.5 compatibility fixes added.
+ * Windows script wrappers now support quoted arguments and arguments
+   containing spaces.  (Patch contributed by Jim Fulton.)
+ * The ```` script now actually works when you put a setuptools
+   ``.egg`` alongside it for bootstrapping an offline machine.
+ * A writable installation directory on ``sys.path`` is no longer required to
+   download and extract a source distribution using ``--editable``.
+ * Generated scripts now use ``-x`` on the ``#!`` line when ``sys.executable``
+   contains non-ASCII characters, to prevent deprecation warnings about an
+   unspecified encoding when the script is run.
+ * EasyInstall now includes setuptools version information in the
+   ``User-Agent`` string sent to websites it visits.
+ * Fix creating Python wrappers for non-Python scripts
+ * Fix ``ftp://`` directory listing URLs from causing a crash when used in the
+   "Home page" or "Download URL" slots on PyPI.
+ * Fix ``sys.path_importer_cache`` not being updated when an existing zipfile
+   or directory is deleted/overwritten.
+ * Fix not recognizing HTML 404 pages from package indexes.
+ * Allow ``file://`` URLs to be used as a package index.  URLs that refer to
+   directories will use an internally-generated directory listing if there is
+   no ``index.html`` file in the directory.
+ * Allow external links in a package index to be specified using
+   ``rel="homepage"`` or ``rel="download"``, without needing the old
+   PyPI-specific visible markup.
+ * Suppressed warning message about possibly-misspelled project name, if an egg
+   or link for that project name has already been seen.
+ * Fix local ``--find-links`` eggs not being copied except with
+   ``--always-copy``.
+ * Fix sometimes not detecting local packages installed outside of "site"
+   directories.
+ * Fix mysterious errors during initial ``setuptools`` install, caused by
+   ``ez_setup`` trying to run ``easy_install`` twice, due to a code fallthru
+   after deleting the egg from which it's running.
+ * Don't install or update a ```` patch when installing to a
+   ``PYTHONPATH`` directory with ``--multi-version``, unless an
+   ``easy-install.pth`` file is already in use there.
+ * Construct ``.pth`` file paths in such a way that installing an egg whose
+   name begins with ``import`` doesn't cause a syntax error.
+ * Fixed a bogus warning message that wasn't updated since the 0.5 versions.
+ * Better ambiguity management: accept ``#egg`` name/version even if processing
+   what appears to be a correctly-named distutils file, and ignore ``.egg``
+   files with no ``-``, since valid Python ``.egg`` files always have a version
+   number (but Scheme eggs often don't).
+ * Support ``file://`` links to directories in ``--find-links``, so that
+   easy_install can build packages from local source checkouts.
+ * Added automatic retry for Sourceforge mirrors.  The new download process is
+   to first just try, then randomly select mirror IPs and
+   remove ones that fail, until something works.  The removed IPs stay removed
+   for the remainder of the run.
+ * Ignore bdist_dumb distributions when looking at download URLs.
+ * Process ``dependency_links.txt`` if found in a distribution, by adding the
+   URLs to the list for scanning.
+ * Use relative paths in ``.pth`` files when eggs are being installed to the
+   same directory as the ``.pth`` file.  This maximizes portability of the
+   target directory when building applications that contain eggs.
+ * Added ``easy_install-N.N`` script(s) for convenience when using multiple
+   Python versions.
+ * Added automatic handling of installation conflicts.  Eggs are now shifted to
+   the front of sys.path, in an order consistent with where they came from,
+   making EasyInstall seamlessly co-operate with system package managers.
+   The ``--delete-conflicting`` and ``--ignore-conflicts-at-my-risk`` options
+   are now no longer necessary, and will generate warnings at the end of a
+   run if you use them.
+ * Don't recursively traverse subdirectories given to ``--find-links``.
+ * Added exhaustive testing of the install directory, including a spawn test
+   for ``.pth`` file support, and directory writability/existence checks.  This
+   should virtually eliminate the need to set or configure ``--site-dirs``.
+ * Added ``--prefix`` option for more do-what-I-mean-ishness in the absence of
+   RTFM-ing.  :)
+ * Enhanced ``PYTHONPATH`` support so that you don't have to put any eggs on it
+   manually to make it work.  ``--multi-version`` is no longer a silent
+   default; you must explicitly use it if installing to a non-PYTHONPATH,
+   non-"site" directory.
+ * Expand ``$variables`` used in the ``--site-dirs``, ``--build-directory``,
+   ``--install-dir``, and ``--script-dir`` options, whether on the command line
+   or in configuration files.
+ * Improved SourceForge mirror processing to work faster and be less affected
+   by transient HTML changes made by SourceForge.
+ * PyPI searches now use the exact spelling of requirements specified on the
+   command line or in a project's ``install_requires``.  Previously, a
+   normalized form of the name was used, which could lead to unnecessary
+   full-index searches when a project's name had an underscore (``_``) in it.
+ * EasyInstall can now download bare ``.py`` files and wrap them in an egg,
+   as long as you include an ``#egg=name-version`` suffix on the URL, or if
+   the ``.py`` file is listed as the "Download URL" on the project's PyPI page.
+   This allows third parties to "package" trivial Python modules just by
+   linking to them (e.g. from within their own PyPI page or download links
+   page).
+ * The ``--always-copy`` option now skips "system" and "development" eggs since
+   they can't be reliably copied.  Note that this may cause EasyInstall to
+   choose an older version of a package than what you expected, or it may cause
+   downloading and installation of a fresh version of what's already installed.
+ * The ``--find-links`` option previously scanned all supplied URLs and
+   directories as early as possible, but now only directories and direct
+   archive links are scanned immediately.  URLs are not retrieved unless a
+   package search was already going to go online due to a package not being
+   available locally, or due to the use of the ``--update`` or ``-U`` option.
+ * Fixed the annoying ``--help-commands`` wart.
+ * Fixed ``.pth`` file processing picking up nested eggs (i.e. ones inside
+   "baskets") when they weren't explicitly listed in the ``.pth`` file.
+ * If more than one URL appears to describe the exact same distribution, prefer
+   the shortest one.  This helps to avoid "table of contents" CGI URLs like the
+   ones on
+ * Quote arguments to python.exe (including python's path) to avoid problems
+   when Python (or a script) is installed in a directory whose name contains
+   spaces on Windows.
+ * Support full roundtrip translation of eggs to and from ``bdist_wininst``
+   format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
+   egg in an .exe that will safely install it as an egg (i.e., with metadata
+   and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
+   back into an ``.egg`` file or directory and install it as such.
+ * Update for changed SourceForge mirror format
+ * Fixed not installing dependencies for some packages fetched via Subversion
+ * Fixed dependency installation with ``--always-copy`` not using the same
+   dependency resolution procedure as other operations.
+ * Fixed not fully removing temporary directories on Windows, if a Subversion
+   checkout left read-only files behind
+ * Fixed some problems building extensions when Pyrex was installed, especially
+   with Python 2.4 and/or packages using SWIG.
+ * Fixed not being able to install Windows script wrappers using Python 2.3
+ * Added support for "traditional" PYTHONPATH-based non-root installation, and
+   also the convenient ```` script, based on a contribution
+   by Ian Bicking.  The setuptools egg now contains a hacked ``site`` module
+   that makes the PYTHONPATH-based approach work with .pth files, so that you
+   can get the full EasyInstall feature set on such installations.
+ * Added ``--no-deps`` and ``--allow-hosts`` options.
+ * Improved Windows ``.exe`` script wrappers so that the script can have the
+   same name as a module without confusing Python.
+ * Changed dependency processing so that it's breadth-first, allowing a
+   depender's preferences to override those of a dependee, to prevent conflicts
+   when a lower version is acceptable to the dependee, but not the depender.
+   Also, ensure that currently installed/selected packages aren't given
+   precedence over ones desired by a package being installed, which could
+   cause conflict errors.
+ * Improved error message when trying to use old ways of running
+   ``easy_install``.  Removed the ability to run via ``python -m`` or by
+   running ````; ``easy_install`` is the command to run on all
+   supported platforms.
+ * Improved wrapper script generation and runtime initialization so that a
+   VersionConflict doesn't occur if you later install a competing version of a
+   needed package as the default version of that package.
+ * Fixed a problem parsing version numbers in ``#egg=`` links.
+ * EasyInstall can now install "console_scripts" defined by packages that use
+   ``setuptools`` and define appropriate entry points.  On Windows, console
+   scripts get an ``.exe`` wrapper so you can just type their name.  On other
+   platforms, the scripts are installed without a file extension.
+ * Using ``python -m easy_install`` or running ```` is now
+   DEPRECATED, since an ``easy_install`` wrapper is now available on all
+   platforms.
+ * EasyInstall now does MD5 validation of downloads from PyPI, or from any link
+   that has an "#md5=..." trailer with a 32-digit lowercase hex md5 digest.
+ * EasyInstall now handles symlinks in target directories by removing the link,
+   rather than attempting to overwrite the link's destination.  This makes it
+   easier to set up an alternate Python "home" directory (as described above in
+   the `Non-Root Installation`_ section).
+ * Added support for handling MacOS platform information in ``.egg`` filenames,
+   based on a contribution by Kevin Dangoor.  You may wish to delete and
+   reinstall any eggs whose filename includes "darwin" and "Power_Macintosh",
+   because the format for this platform information has changed so that minor
+   OS X upgrades (such as 10.4.1 to 10.4.2) do not cause eggs built with a
+   previous OS version to become obsolete.
+ * easy_install's dependency processing algorithms have changed.  When using
+   ``--always-copy``, it now ensures that dependencies are copied too.  When
+   not using ``--always-copy``, it tries to use a single resolution loop,
+   rather than recursing.
+ * Fixed installing extra ``.pyc`` or ``.pyo`` files for scripts with ``.py``
+   extensions.
+ * Added ``--site-dirs`` option to allow adding custom "site" directories.
+   Made ``easy-install.pth`` work in platform-specific alternate site
+   directories (e.g. ``~/Library/Python/2.x/site-packages`` on Mac OS X).
+ * If you manually delete the current version of a package, the next run of
+   EasyInstall against the target directory will now remove the stray entry
+   from the ``easy-install.pth`` file.
+ * EasyInstall now recognizes URLs with a ``#egg=project_name`` fragment ID
+   as pointing to the named project's source checkout.  Such URLs have a lower
+   match precedence than any other kind of distribution, so they'll only be
+   used if they have a higher version number than any other available
+   distribution, or if you use the ``--editable`` option.  The ``#egg``
+   fragment can contain a version if it's formatted as ``#egg=proj-ver``,
+   where ``proj`` is the project name, and ``ver`` is the version number.  You
+   *must* use the format for these values that the ``bdist_egg`` command uses;
+   i.e., all non-alphanumeric runs must be condensed to single underscore
+   characters.
+ * Added the ``--editable`` option; see `Editing and Viewing Source Packages`_
+   above for more info.  Also, slightly changed the behavior of the
+   ``--build-directory`` option.
+ * Fixed the setup script sandbox facility not recognizing certain paths as
+   valid on case-insensitive platforms.
+ * Fix ``python -m easy_install`` not working due to setuptools being installed
+   as a zipfile.  Update safety scanner to check for modules that might be used
+   as ``python -m`` scripts.
+ * Misc. fixes for win32.exe support, including changes to support Python 2.4's
+   changed ``bdist_wininst`` format.
+ * Put the ``easy_install`` module back in as a module, as it's needed for
+   ``python -m`` to run it!
+ * Allow ``--find-links/-f`` to accept local directories or filenames as well
+   as URLs.
+ * EasyInstall now automatically detects when an "unmanaged" package or
+   module is going to be on ``sys.path`` ahead of a package you're installing,
+   thereby preventing the newer version from being imported.  By default, it
+   will abort installation to alert you of the problem, but there are also
+   new options (``--delete-conflicting`` and ``--ignore-conflicts-at-my-risk``)
+   available to change the default behavior.  (Note: this new feature doesn't
+   take effect for egg files that were built with older ``setuptools``
+   versions, because they lack the new metadata file required to implement it.)
+ * The ``easy_install`` distutils command now uses ``DistutilsError`` as its
+   base error type for errors that should just issue a message to stderr and
+   exit the program without a traceback.
+ * EasyInstall can now be given a path to a directory containing a setup
+   script, and it will attempt to build and install the package there.
+ * EasyInstall now performs a safety analysis on module contents to determine
+   whether a package is likely to run in zipped form, and displays
+   information about what modules may be doing introspection that would break
+   when running as a zipfile.
+ * Added the ``--always-unzip/-Z`` option, to force unzipping of packages that
+   would ordinarily be considered safe to unzip, and changed the meaning of
+   ``--zip-ok/-z`` to "always leave everything zipped".
+ * There is now a separate documentation page for `setuptools`_; revision
+   history that's not specific to EasyInstall has been moved to that page.
+ .. _setuptools:
+ * Made ``easy_install`` a standard ``setuptools`` command, moving it from
+   the ``easy_install`` module to ``setuptools.command.easy_install``.  Note
+   that if you were importing or extending it, you must now change your imports
+   accordingly.  ```` is still installed as a script, but not as
+   a module.
+ * Added ``--always-copy/-a`` option to always copy needed packages to the
+   installation directory, even if they're already present elsewhere on
+   sys.path. (In previous versions, this was the default behavior, but now
+   you must request it.)
+ * Added ``--upgrade/-U`` option to force checking PyPI for latest available
+   version(s) of all packages requested by name and version, even if a matching
+   version is available locally.
+ * Added automatic installation of dependencies declared by a distribution
+   being installed.  These dependencies must be listed in the distribution's
+   ``EGG-INFO`` directory, so the distribution has to have declared its
+   dependencies by using setuptools.  If a package has requirements it didn't
+   declare, you'll still have to deal with them yourself.  (E.g., by asking
+   EasyInstall to find and install them.)
+ * Added the ``--record`` option to ``easy_install`` for the benefit of tools
+   that run `` install --record=filename`` on behalf of another
+   packaging system.)
+ * Fixed not setting script permissions to allow execution.
+ * Improved sandboxing so that setup scripts that want a temporary directory
+   (e.g. pychecker) can still run in the sandbox.
+ * Fix stupid stupid refactoring-at-the-last-minute typos.  :(
+ * Added support for converting ``.win32.exe`` installers to eggs on the fly.
+   EasyInstall will now recognize such files by name and install them.
+ * Fixed a problem with picking the "best" version to install (versions were
+   being sorted as strings, rather than as parsed values)
+ * Added support for the distutils "verbose/quiet" and "dry-run" options, as
+   well as the "optimize" flag.
+ * Support downloading packages that were uploaded to PyPI (by scanning all
+   links on package pages, not just the homepage/download links).
+ * Add progress messages to the search/download process so that you can tell
+   what URLs it's reading to find download links.  (Hopefully, this will help
+   people report out-of-date and broken links to package authors, and to tell
+   when they've asked for a package that doesn't exist.)
+ * Added support for installing scripts
+ * Added support for setting options via distutils configuration files, and
+   using distutils' default options as a basis for EasyInstall's defaults.
+ * Renamed ``--scan-url/-s`` to ``--find-links/-f`` to free up ``-s`` for the
+   script installation directory option.
+ * Use ``urllib2`` instead of ``urllib``, to allow use of ``https:`` URLs if
+   Python includes SSL support.
+ * Added ``--scan-url`` and ``--index-url`` options, to scan download pages
+   and search PyPI for needed packages.
+ * Restrict ``--build-directory=DIR/-b DIR`` option to only be used with single
+   URL installs, to avoid running the wrong
+ * Added ``--build-directory=DIR/-b DIR`` option.
+ * Added "installation report" that explains how to use 'require()' when doing
+   a multiversion install or alternate installation directory.
+ * Added SourceForge mirror auto-select (Contributed by Ian Bicking)
+ * Added "sandboxing" that stops a setup script from running if it attempts to
+   write to the filesystem outside of the build area
+ * Added more workarounds for packages with quirky ``install_data`` hacks
+ * Added subversion download support for ``svn:`` and ``svn+`` URLs, as well as
+   automatic recognition of HTTP subversion URLs (Contributed by Ian Bicking)
+ * Misc. bug fixes
+ * Initial release.
+Future Plans
+* Additional utilities to list/remove/verify packages
+* Signature checking?  SSL?  Ability to suppress PyPI search?
+* Display byte progress meter when downloading distributions and long pages?
+* Redirect stdout/stderr to log during run_setup?

-Easy Install
-Easy Install is a python module (``easy_install``) bundled with ``setuptools``
-that lets you automatically download, build, install, and manage Python
-Please share your experiences with us! If you encounter difficulty installing
-a package, please contact us via the `distutils mailing list
-<>`_.  (Note: please DO NOT send
-private email directly to the author of setuptools; it will be discarded.  The
-mailing list is a searchable archive of previously-asked and answered
-questions; you should begin your research there before reporting something as a
-bug -- and then do so via list discussion first.)
-(Also, if you'd like to learn about how you can use ``setuptools`` to make your
-own packages work better with EasyInstall, or provide EasyInstall-like features
-without requiring your users to use EasyInstall directly, you'll probably want
-to check out the full `setuptools`_ documentation as well.)
-.. contents:: **Table of Contents**
-Using "Easy Install"
-.. _installation instructions:
-Installing "Easy Install"
-Please see the `setuptools PyPI page <>`_
-for download links and basic installation instructions for each of the
-supported platforms.
-You will need at least Python 2.3.5, or if you are on a 64-bit platform, Python
-2.4.  An ``easy_install`` script will be installed in the normal location for
-Python scripts on your platform.
-Note that the instructions on the setuptools PyPI page assume that you are
-are installling to Python's primary ``site-packages`` directory.  If this is
-not the case, you should consult the section below on `Custom Installation
-Locations`_ before installing.  (And, on Windows, you should not use the
-``.exe`` installer when installing to an alternate location.)
-Note that ``easy_install`` normally works by downloading files from the
-internet.  If you are behind an NTLM-based firewall that prevents Python
-programs from accessing the net directly, you may wish to first install and use
-the `APS proxy server <>`_, which lets you get past such
-firewalls in the same way that your web browser(s) do.
-(Alternately, if you do not wish easy_install to actually download anything, you
-can restrict it from doing so with the ``--allow-hosts`` option; see the
-sections on `restricting downloads with --allow-hosts`_ and `command-line
-options`_ for more details.)
-If EasyInstall/setuptools appears to install correctly, and you can run the
-``easy_install`` command but it fails with an ``ImportError``, the most likely
-cause is that you installed to a location other than ``site-packages``,
-without taking any of the steps described in the `Custom Installation
-Locations`_ section below.  Please see that section and follow the steps to
-make sure that your custom location will work correctly.  Then re-install.
-Similarly, if you can run ``easy_install``, and it appears to be installing
-packages, but then you can't import them, the most likely issue is that you
-installed EasyInstall correctly but are using it to install packages to a
-non-standard location that hasn't been properly prepared.  Again, see the
-section on `Custom Installation Locations`_ for more details.
-Windows Notes
-On Windows, an ``easy_install.exe`` launcher will also be installed, so that
-you can just type ``easy_install`` as long as it's on your ``PATH``.  If typing
-``easy_install`` at the command prompt doesn't work, check to make sure your
-``PATH`` includes the appropriate ``C:\\Python2X\\Scri
