 Build instructions
-------------------
+==================
 
 Before you start building Python, you must first configure it.  This
 entails (at least) running the script "./configure", which figures out
-your system configuration and creates several Makefiles.  (This will
-take a minute or two -- please be patient!)  When it is done, you are
-ready to run make.  Typing "make" in the toplevel directory will
-recursively run make in each of the subdirectories Parser, Objects,
-Python and Modules, creating a library file in each one.  The
-executable of the interpreter is built in the Modules subdirectory but
-moved up here when it is built.  If you want or need to, you can also
-chdir into each subdirectory in turn and run make there manually
-(do the Modules subdirectory last!).  If you run into trouble, first
-see the section Troubleshooting later in this file.

-AIX users: read the file Misc/AIX-NOTES before trying to build.
+NOTE: if you rerun the configure script with different options, remove
+all object files by running "make clean" before rebuilding.  Believe
+it or not, "make clean" sometimes helps to clean up other inexplicable
+problems as well.  Try it before sending in a bug report!
 
-HP-UX users: read the file Misc/HPUX-NOTES if you want to be able to
-use shared libraries for dynamically loaded modules.
 
-DEC Alpha users: unless you like debugging GCC, pass "--without-gcc"
-to the configure script.
+Troubleshooting
+---------------
 
-Minix users: when using ack, use "CC=cc AR=aal RANLIB=: ./configure"!
+If you run into trouble, see section 3 of the FAQ (file Misc/FAQ) for
+hints on what can go wrong, and how to fix it.
+
+
+Platform specific notes
+-----------------------
+
+Linux:	It is possible that "makesetup" fails with an obscure sed
+	error.  This is a bug in bash.  Replace /bin/sh with /bin/ash
+	in both makesetup and Makefile.pre.in.  This has been observed
+	in Slackware version 2.2, bash 1.14.3; Slackware 2.1 did not
+	have the problem.
+
+AIX:	Read the file Misc/AIX-NOTES before trying to build.
+
+HP-UX:	Read the file Misc/HPUX-NOTES if you want to be able to
+	use shared libraries for dynamically loaded modules.
+
+Minix:	When using ack, use "CC=cc AR=aal RANLIB=: ./configure"!
+
+SCO:	1) Everything works much better if you add -U__STDC__ to the
+	defs.  This is because all the SCO header files are broken.
+	Anything that isn't mentioned in the C standard it's
+	conditionally excluded when __STDC__ is defined.
+
+	2) Due to the U.S. export restrictions, SCO broke the crypt
+	stuff out into a separate library, libcrypt_i.a so the LIBS
+	needed be set to:
+
+		LIBS=' -lsocket -lcrypt_i'
+
+
+Configuring the set of built-in modules
+---------------------------------------
 
 You can configure the interpreter to contain fewer or more built-in
 modules by editing the file Modules/Setup.  This file is initially
 will automatically be rebuilt the next time you run make in the
 toplevel directory.
 
-If you want to change the optimization level of the build, assign to
-the OPT variable on the toplevel make command; e.g. "make OPT=-g" will
-build a debugging version of Python on most platforms.  The default is
-OPT=-O; a value for OPT in the environment when the configure script
-is run overrides this default (likewise for CC; and the initial value
-for LIBS is used as the base set of libraries to link with).
+Especially on SGI IRIX, there are modules that interface to many SGI
+specific system libraries, e.g. the GL library and the audio hardware.
+
+
+Setting the optimization/debugging options
+------------------------------------------
+
+If you want to change the optimization/debugging options for the C
+compiler, assign to the OPT variable on the toplevel make command;
+e.g. "make OPT=-g" will build a debugging version of Python on most
+platforms.  The default is OPT=-O; a value for OPT in the environment
+when the configure script is run overrides this default (likewise for
+CC; and the initial value for LIBS is used as the base set of
+libraries to link with).
+
+
+Testing
+-------
 
 To test the interpreter that you have just built, type "make test".
 This runs the test set silently, twice (once with no compiled files,
 does not test the built-in modules, but will find most other problems
 with the interpreter.)
 
+IMPORTANT: If the tests fail and you decide to mail a bug report,
+*don't* include the output of "make test".  It is useless.  Run the
+following command instead:
+
+	PYTHONPATH=../Lib:../Lib/test:./Modules ./python -c 'import testall'
+
+(substituting the top of the source tree for .. if you built in a
+different directory).  This gives the output of the tests and shows
+which test failed.
+
+
+Installing
+----------
+
 To install the interpreter as /usr/local/bin/python, type "make
 install".  To install the library as /usr/local/lib/python, type "make
 libinstall".  To install the manual page as
 used or produced during the build process which are needed to build
 extensions or to generate their Makefiles.
 
-To print the documentation, cd into the Doc subdirectory, type "make"
-(let's hope you have LaTeX installed!), and send the four resulting
-PostScript files (tut.ps, lib.ps, ref.ps, and ext.ps) to the printer.
-See the README file there; you can also build a texinfo version of the
-library manual and from that construct an Emacs info version (the
-hypertext format used by the Emacs "info" command) and an HTML version
-(the hypertext format used by the World Wide Web distributed
-information initiative).  You don't need to have LaTeX installed for
-this.  Note that the Python archive sites also carry the resulting
-PostScript files, in case you have a PostScript printer but not LaTeX.
+
+Configuration options and variables
+-----------------------------------
 
 Some special cases are handled by passing environment variables or
-options to the configure script:
+options to the configure script.
 
-- The configure script uses gcc (the GNU C compiler) if it finds it.
-If you don't want this, or if this compiler is installed but broken on
-your platform, pass the option --without-gcc.  You can also pass
-"CC=cc" (or whatever the name of the proper C compiler is) in the
-environment, but the advantage of using --without-gcc is that this
-option is remembered by the config.status script for its --recheck
-option.
+NOTE: if you rerun the configure script with different options, remove
+all object files by running "make clean" before rebuilding.
 
-- On SCO, a number of notes apply:
+--with(out)-gcc: The configure script uses gcc (the GNU C compiler) if
+	it finds it.  If you don't want this, or if this compiler is
+	installed but broken on your platform, pass the option
+	--without-gcc.  You can also pass "CC=cc" (or whatever the
+	name of the proper C compiler is) in the environment, but the
+	advantage of using --without-gcc is that this option is
+	remembered by the config.status script for its --recheck
+	option.
 
-	1) Everything works much better if you add -U__STDC__ to the
-	defs.  This is because all the SCO header files are broken.
-	Anything that isn't mentioned in the C standard it's
-	conditionally excluded when __STDC__ is defined.
+--prefix, --exec-prefix: If you want to install the binaries and the
+	Python library somewhere else than in /usr/local/{bin,lib},
+	you can pass the option --prefix=DIRECTORY; the interpreter
+	binary will be installed as DIRECTORY/bin/python and the
+	library files as DIRECTORY/lib/python/*.  If you pass
+	--exec-prefix=DIRECTORY (as well) this overrides the
+	installation prefix for architecture-dependent files (like the
+	interpreter binary).  Note that --prefix=DIRECTORY also
+	affects the default module search path (sys.path), when
+	Modules/config.c is compiled.  Passing make the option
+	prefix=DIRECTORY (and/or exec_prefix=DIRECTORY) overrides the
+	prefix set at configuration time; this may be more convenient
+	than re-running the configure script if you change your mind
+	about the install prefix...
 
-	2) Due to the U.S. export restrictions, SCO broke the crypt
-	stuff out into a separate library, libcrypt_i.a so the LIBS
-	needed be set to:
+--with-readline: You can use the GNU readline library to improve the
+	interactive user interface: this gives you line editing and
+	command history when calling python interactively.  You need
+	to configure build the GNU readline library before running the
+	configure script.  Its sources are not distributed with
+	Python; you can ftp them from any GNU mirror site, or from its
+	home site:
+	<URL:ftp://slc2.ins.cwru.edu/pub/dist/readline-2.0.tar.gz> (or
+	a higher version number -- using version 1.x is not
+	recommended).
 
-		LIBS=' -lsocket -lcrypt_i'
+	A GPL-free version was posted to comp.sources.misc in volume
+	31 and is widely available from FTP archive sites, e.g.
+	<URL:ftp://gatekeeper.dec.com/.b/usenet/comp.sources.misc/
+	volume31/editline/part01.Z>
 
+	Pass the Python configure script the option
+	--with-readline=DIRECTORY where DIRECTORY is the absolute
+	pathname of the directory where you've built the readline
+	library.  Some hints on building and using the readline
+	library are in the FAQ (file Misc/FAQ).
 
-- If you want to install the binaries and the Python library somewhere
-else than in /usr/local/{bin,lib}, you can pass the option
---prefix=DIRECTORY; the interpreter binary will be installed as
-DIRECTORY/bin/python and the library files as DIRECTORY/lib/python/*.
-If you pass --exec-prefix=DIRECTORY (as well) this overrides the
-installation prefix for architecture-dependent files (like the
-interpreter binary).  Note that --prefix=DIRECTORY also affects the
-default module search path (sys.path), when Modules/config.c is
-compiled.  Passing make the option prefix=DIRECTORY (and/or
-exec_prefix=DIRECTORY) overrides the prefix set at configuration time;
-this may be more convenient than re-running the configure script if
-you change your mind about the install prefix...
+--with-thread: On SGI IRIX, and on Sun SOLARIS 2, you can use multiple
+	threads.  To enable this, pass --with-thread.  In the
+	Modules/Setup file, enable the thread module.  (Threads aren't
+	enabled automatically because there are run-time penalties
+	when support for them is compiled in even if you don't use
+	them.)
 
-- You can use the GNU readline library to improve the interactive user
-interface: this gives you line editing and command history when
-calling python interactively.  You need to configure build the GNU
-readline library before running the configure script.  Its sources are
-not distributed with Python; you can ftp them from any GNU mirror
-site, or from its home site:
-<URL:ftp://slc2.ins.cwru.edu/pub/dist/readline-2.0.tar.gz> (or a
-higher version number -- using version 1.x is not recommended).
+--with-sgi-dl: On SGI IRIX 4, dynamic loading of extension modules is
+	supported by the "dl" library by Jack Jansen, which is
+	ftp'able from <URL:ftp://ftp.cwi.nl/pub/dynload/dl-1.6.tar.Z>.
+	This is enabled (after you've ftp'ed and compiled the dl
+	library!) by passing --with-sgi-dl=DIRECTORY where DIRECTORY
+	is the absolute pathname of the dl library.  (Don't bother on
+	IRIX 5, it already has dynamic linking using SunOS style
+	shared libraries.)  Support for this feature is deprecated.
 
-A GPL-free version was posted to comp.sources.misc in volume 31 and is
-widely available from FTP archive sites, e.g.
-<URL:ftp://gatekeeper.dec.com/.b/usenet/comp.sources.misc/volume31/editline/part01.Z>
+--with-dl-dld: Dynamic loading of modules is rumoured to be supported
+	on some other systems: VAX (Ultrix), Sun3 (SunOS 3.4), Sequent
+	Symmetry (Dynix), and Atari ST.  This is done using a
+	combination of the GNU dynamic loading package
+	(<URL:ftp://ftp.cwi.nl/pub/dynload/dl-dld-1.1.tar.Z>) and an
+	emulation of the SGI dl library mentioned above (the emulation
+	can be found at
+	<URL:ftp://ftp.cwi.nl/pub/dynload/dld-3.2.3.tar.Z>).  To
+	enable this, ftp and compile both libraries, then call the
+	configure passing it the option
+	--with-dl-dld=DL_DIRECTORY,DLD_DIRECTORY where DL_DIRECTORY is
+	the absolute pathname of the dl emulation library and
+	DLD_DIRECTORY is the absolute pathname of the GNU dld library.
+	(Don't bother on SunOS 4 or 5, they already have dynamic
+	linking using shared libraries.)  Support for this feature is
+	deprecated.
 
-Pass the Python configure script the option --with-readline=DIRECTORY
-where DIRECTORY is the absolute pathname of the directory where you've
-built the readline library.  Some hints on building and using the
-readline library:
+--with-libm, --with-libc: It is possible to specify alternative
+	versions for the Math library (default -lm) and the C library
+	(default the empty string) using the options
+	--with-libm=STRING and --with-libc=STRING, respectively.  E.g.
+	if your system requires that you pass -lc_s to the C compiler
+	to use the shared C library, you can pass --with-libc=-lc_s.
+	These libraries are passed after all other libraries, the C
+	library last.
 
-    - If you have already built Python without readline and then
-    decide to add it, you have to rerun configure adding the
-    --with-readline flag, AND you have to remove the object file
-    Modules/myreadline.o (same if you go the other way)
 
-    - On SGI IRIX 5, you may have to add the following
-    to rldefs.h:
-
-	#ifndef sigmask
-	#define sigmask(sig)	(1L << ((sig)-1))
-	#endif
-
-    - On most systems, you will have to add #include "rldefs.h" to the
-    top of several source files, and if you use the VPATH feature, you
-    will have to add dependencies of the form foo.o: foo.c to the
-    Makefile for several values of foo.
-
-    - The readline library requires use of the termcap library.  A
-    known problem with this is that it contains entry points which
-    cause conflicts with the STDWIN and SGI GL libraries.  The stdwin
-    conflict can be solved (and will be, in the next release of
-    stdwin) by adding a line saying '#define werase w_erase' to the
-    stdwin.h file (in the stdwin distribution, subdirectory H).  The
-    GL conflict has been solved in the Python configure script by a
-    hack that forces use of the static version of the termcap library.
-
-    - Check the newsgroup gnu.bash.bugs for specific problems with the
-    readline library (I don't get this group here but I've been told
-    that it is the place for readline bugs.)
-
-- On SGI IRIX, and on Sun SOLARIS 2, you can use multiple threads.  To
-enable this, pass --with-thread.  In the Modules/Setup file, enable
-the thread module.  (Threads aren't enabled automatically because
-there are run-time penalties when support for them is compiled in even
-if you don't use them.)
-
-- On SGI IRIX, there are modules that interface to many SGI specific
-system libraries, e.g. the GL library and the audio hardware.  To
-enable these modules, you must edit the Modules/Setup file (or copy the
-Setup.irix4 file to it).

-- On SGI IRIX 4, dynamic loading of extension modules is supported by
-the "dl" library by Jack Jansen, which is ftp'able from
-<URL:ftp://ftp.cwi.nl/pub/dynload/dl-1.6.tar.Z>.  This is enabled
-(after you've ftp'ed and compiled the dl library!) by passing
---with-sgi-dl=DIRECTORY where DIRECTORY is the absolute pathname of
-the dl library.  (Don't bother on IRIX 5, it already has dynamic
-linking using SunOS style shared libraries.)  Support for this feature
-is deprecated.
-
-- Dynamic loading of modules is rumoured to be supported on some other
-systems: VAX (Ultrix), Sun3 (SunOS 3.4), Sequent Symmetry (Dynix), and
-Atari ST.  This is done using a combination of the GNU dynamic loading
-package (<URL:ftp://ftp.cwi.nl/pub/dynload/dl-dld-1.1.tar.Z>) and an
-emulation of the SGI dl library mentioned above (the emulation can be
-found at <URL:ftp://ftp.cwi.nl/pub/dynload/dld-3.2.3.tar.Z>).  To enable
-this, ftp and compile both libraries, then call the configure passing
-it the option --with-dl-dld=DL_DIRECTORY,DLD_DIRECTORY where
-DL_DIRECTORY is the absolute pathname of the dl emulation library and
-DLD_DIRECTORY is the absolute pathname of the GNU dld library.  (Don't
-bother on SunOS 4 or 5, they already have dynamic linking using shared
-libraries.)  Support for this feature is deprecated.
-
-- It is possible to specify alternative versions for the Math library
-(default -lm) and the C library (default the empty string) using the
-options --with-libm=STRING and --with-libc=STRING, respectively.  E.g.
-if your system requires that you pass -lc_s to the C compiler to use
-the shared C library, you can pass --with-libc=-lc_s.  These libraries
-are passed after all other libraries, the C library last.
+Extensions
+----------
 
 You can also build an "extended" interpreter, using modules that are
 not contained in the Modules directory.  Extensions are distributed as
-a separate tar file (currently extensions.tar.Z).  See the README file
-there.
-
-
-The Tk extension
-----------------
-
-Tk (the user interface component of John Ousterhout's Tcl language) is
-also usable from Python.  Since this requires that you first build and
-install Tcl/Tk, the Tk interface is not enabled by default.  It
-requires Tcl 7.3 and Tk 3.6.  For more info about Tk, including
-pointers to the source, see John Ousterhout's home page at
-<URL:http://playground.sun.com/~ouster/>.
-
-To enable the Python/Tk interface, once you've built and installed
-Tcl/Tk, all you need to do is edit two lines in Modules/Setup; search
-for the string "Tk".  Un-comment one (normally the first) of the lines
-beginning with "#tkinter" and un-comment the line beginning with
-"#TKPATH".  (If you have installed Tcl/Tk in unusual places you will
-have to edit the first line as well to fix the -I and -L options.)
-See the Build Instructions above for more details.
-
-There is little documentation.  Begin with fetching the "Tk Lifesaver"
-document, e.g. <URL:ftp://ftp.cwi.nl/pub/python/tkinter-doc.tar.gz> (a
-gzipped tar file containing a PostScript file).  There are demos in
-the Demo/tkinter directory, in the subdirectories guido, matt and www.
-
-Note that there's a Python module called "Tkinter" (capital T) which
-lives in Lib/tkinter/Tkinter.py, and a C module called "tkinter"
-(lower case t) which lives in Modules/tkintermodule.c.  Demos and
-normal Tk applications only import the Python Tkinter module -- only
-the latter uses the C tkinter module directly.  In order to find the C
-tkinter module, it must be compiled and linked into the Python
-interpreter -- the tkinter line in the Setup file does this.  In order
-to find the Python Tkinter module, sys.path must be set correctly --
-the TKPATH assignment in the Setup file takes care of this, but only
-if you install Python properly ("make install libinstall").  (You can
-also use dynamic loading for the C tkinter module, in which case you
-must manually fix up sys.path or set $PYTHONPATH for the Python
-Tkinter module.)

+Miscellaneous issues
+====================
+
+
+Documentation
+-------------
+
+All documentation is provided in the subdirectory Doc in the form of
+LaTeX files.  In order of importance for new users: Tutorial (tut),
+Library Reference (lib), Language Reference (ref), Extending (ext).
+Especially the Library Reference is of immense value since much of
+Python's power (including the built-in data types and functions!) is
+described here.
+
+To print the documentation from the LaTeX files, chdir into the Doc
+subdirectory, type "make" (let's hope you have LaTeX installed!), and
+send the four resulting PostScript files (tut.ps, lib.ps, ref.ps, and
+ext.ps) to the printer.  See the README file there.
+
+All documentation is also available on-line via the World-Wide Web
+(WWW): <URL:http://www.cwi.nl/~guido/Python.html>.  It can also be
+downloaded separately from the ftp archives (see below) in Emacs INFO,
+HTML or PostScript form -- see the FAQ (file Misc/FAQ) for more info.
+
+
+Emacs mode
+----------
+
+There's an excellent Emacs editing mode for Python code; see the file
+Misc/python-mode.el.  Originally written by Tim Peters, who's no
+longer on the net, it is now maintained by Barry Warsaw
+<bwarsaw@cnri.reston.va.com>.
+
+
+Bug reports
+-----------
+
+Bugs are best reported to the comp.lang.python newsgroup or the Python
+mailing list -- see the section "Newsgroup and mailing list" below.
+Before posting, read the FAQ (file Misc/FAQ) first to see if your
+problem has already been answered!
+
+
+Ftp access
+----------
+
+Python's "home ftp site" is ftp.cwi.nl, directory pub/python.  See the
+FAQ (file Misc/FAQ) for a list of other ftp sites carrying the Python
+distribution.
+
+
+Newsgroup and mailing list
+--------------------------
+
+There are a newsgroup and a mailing list devoted to Python
+programming, design and bugs.  The newsgroup, comp.lang.python,
+contains exactly the same messages as the mailing list.  To subscribe
+to the mailing list, send mail containing your real name and e-mail
+address to "python-list-request@cwi.nl" (a real person reads these
+messages, so no LISTPROC or Majordomo commands, please).
+
+
+The Tk interface
+----------------
+
+Tk (the user interface component of John Ousterhout's Tcl language) is
+also usable from Python.  Since this requires that you first build and
+install Tcl/Tk, the Tk interface is not enabled by default.  It
+requires Tcl 7.3 and Tk 3.6.  It doesn't work yet with Tk 4.0-beta!
+(Actually, the C code does, but the Tkinter.py module hasn't been
+adapted yet.)  For more info about Tk, including pointers to the
+source, see John Ousterhout's home page at
+<URL:http://playground.sun.com/~ouster/>.
+
+To enable the Python/Tk interface, once you've built and installed
+Tcl/Tk, all you need to do is edit two lines in Modules/Setup; search
+for the string "tkinter".  Un-comment one (normally the first) of the
+lines beginning with "#tkinter" and un-comment the line beginning with
