hgsubversion is an extension for Mercurial that allows using Mercurial
as a Subversion client.

At this point, hgsubversion is usable by users reasonably familiar with
Mercurial as a VCS. It's not recommended to dive into hgsubversion as an
introduction to Mercurial, since hgsubversion "bends the rules" a little
and violates some of the typical assumptions of early Mercurial users.

You need to have Subversion installed with the SWIG Python bindings
from Subversion 1.5 or later. You need Mercurial 1.3 or later.

If you are unfamiliar with installing Mercurial extensions, please see
the UsingExtensions_ page in the Mercurial wiki. Look at the example
for specifying an absolute path near the bottom of the page. You want
to give the path to the top level of your clone of this repository.

Before using hgsubversion, I *strongly* encourage you to run the
automated tests. Just use nose_ if you have it (or ``easy_install
nose`` if you want it), or use ``python tests/run.py`` to run the
suite with the conventional test runner. Note that because I use nose,
there's a lot of stdout spew in the tests right now. The important
part is that all the tests pass.

Basic Use
Get a new clone of an svn server::

 $ hg clone <svn URI> [destination]

Real example::

 $ hg clone http://python-nose.googlecode.com/svn nose-hg

Note, you should pull from the root subversion directory, not specific
folders (such as trunk).

Pull new revisions into an already-converted repo::

 $ hg pull

For more information, see ``hg help svn`` while in a converted repo.

Support for ``svn:externals``
All ``svn:externals`` properties are serialized into a single
``.hgsvnexternals`` file having the following syntax::

   common1 http://path/to/external/svn/repo1
   ...additional svn:externals properties lines...
   common2 -r123 http://path/to/external/svn/repo2
   ...additional svn:externals properties lines...

A header line in brackets specifies the directory the property applies
to, where '.' indicates the project root directory. The property content
follows the header, **with every content line being prefixed by a single
space**. Note that the property lines have a format identical to
svn:externals properties as used in Subversion, and do not support the
hgsubversion extended svn+http:// URL format.

Issuing the command ``hg svn updateexternals`` with the
``.hgsvnexternals`` example above would fetch the latest revision of
repo1 into the subdirectory ./common1, and revision 123 of repo2 into
dir2/common2.  Note that ``.hgsvnexternals`` must be tracked by Mercurial
before this will work.  If ``.hgsvnexternals`` is created or changed, it
will not be pushed to the related Subversion repository, *but its
contents will be used to update ``svn:externals`` properties on the
related Subversion repository*.
Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
