Python source distribution is run at build time, and attempts to
discover which modules can be enabled by examining the modules and
! header files on the system. In 2.1alpha1, there's very little you can
! do to change \file{setup.py}'s behaviour, or to discover why a given
! module isn't compiled. If you run into problems in 2.1alpha1, please
! report them, and be prepared to dive into \file{setup.py} in order to
! fix autodetection of a given library on your system. In the alpha2
! release I plan to add ways to have more control over what the script
! does (probably command-line arguments to \file{configure} or to
! \file{setup.py}).
!
! If it turns out to be impossible to make autodetection work reliably,
! it's possible that this change may become an optional build method
! instead of the default, or it may even be backed out completely.
In another far-reaching change to the build mechanism, Neil
Schemenauer restructured things so Python now uses a single makefile
that isn't recursive, instead of makefiles in the top directory and in
! each of the Python/, Parser/, Objects/, and Modules/ subdirectories.
! This makes building Python faster, and also makes the build process
! clearer and simpler.

Python source distribution is run at build time, and attempts to

! header files on the system. If a module is configured in
! \file{Modules/Setup}, the \file{setup.py} script won't attempt to
! compile that module and will defer to the \file{Modules/Setup} file's
! contents. This provides a way to specific any strange command-line
! flags or libraries that are required for a specific platform.

\section{PEP 235: Case-Insensitive Platforms and \keyword{import}}
! XXX
%======================================================================
--- 422,438 ----
\section{PEP 235: Case-Insensitive Platforms and \keyword{import}}
! Some operating systems have filesystems that are case-insensitive,
! MacOS and Windows being the primary examples; on these systems, it's
! impossible to distinguish the filenames \samp{FILE.PY} and
! \samp{file.py}, even though they do store the file's name
! in its original case (they're case-preserving, too).
!
! In Python 2.1, the \keyword{import} statement will work to simulate
! case-sensitivity on case-insensitive platforms. Python will now
! search for the first case-sensitive match by default, raising an
! \exception{ImportError} if no such file is found, so \code{import file}
! will not import a module named \samp{FILE.PY}. Case-insensitive
! matching can be requested by setting the PYTHONCASEOK environment
! variable before starting the Python interpreter.
