directory tree instead of overwriting the input files. Adds three command
line options: -o/--output-dir, -W/--write-unchanged-files and --add-suffix.
Feature backports into stable release branches for 2to3 are allowed by
a special exemption:

The code used to call os.path.join to build a regex but without escaping
the backslash, which lead to test failures on Windows. Antoine Pitrou
fixed it in 0a94e2f807c7 by enhancing the code to accept both / and \,
with proper escaping, but in my opinion this goes against the distutils
feature freeze, hence this change.
Distutils-based packages with C extension modules may fail because
Apple has removed gcc-4.2, the version used to build python.org
64-bit/32-bit Pythons. If the user does not explicitly override
the default C compiler by setting the CC environment variable,
Distutils will now attempt to compile extension modules with clang
if gcc-4.2 is required but not found. Also as a convenience, if
the user does explicitly set CC, substitute its value as the default
compiler in the Distutils LDSHARED configuration variable for OS X.
(Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
SDK, neither of which are available in Xcode 4. This change does not
attempt to override settings to support their use with Xcode 4.)
The contents of this attribute are an implementation detail, as
documented for #9442, so we should not parse it, to support non-CPython
VMs with distutils2 in the future.
Unfortunately, one use comes directly from PEP 345, so an edit will have
to be agreed before fixing the code (see comment in p7g.markers).
Other remaining uses are found in p7g.compiler and could be replaced by
the platform module (which also parses sys.version, but then it wouldn’t
be my fault :)
- Change the fixers used in tests to something not provided by lib2to3
- Test conversion of doctests in text files
- Factor out test boilerplate into a common method
This fixes a regression from distutils, where “setup.py --help-commands”
prints out commands grouped by topic (i.e. building vs. installing),
which is more useful than using sorted.
