- DistutilsOptionError is now documented as it's actually used, ie.
    to indicate bogus option values (usually user options, eg. from
    the command-line)
  - added DistutilsSetupError to indicate errors that definitely arise
    in the setup script
  - got rid of DistutilsValueError, and changed all usage of it to
    either DistutilsSetupError or ValueError as appropriate
  - simplified a bunch of option get/set methods in Command and
    Distribution classes -- just pass on AttributeError most of
    the time, rather than turning it into something else

with ":".

rather than cobbling them togethere here.

'native_path()'.

  than we actually use, and do actually use AR and SO.
Run ranlib on static libraries.  (Should probably have a platform-check
  so we don't run ranlib when it's not necessary, ie. on most modern
  Unices.)

on Unix either, so should probably disappear entirely.)

to account for it not being defined in the constructor.

  crashing when self.force not defined.
Revise 'copy_file()' and 'copy_tree()' docstrings accordingly.
Remove 'hasattr()' check for 'self.force' from 'make_file()'.

'get_python_lib()'.

timestamps), so every build_* command has 'self.force', which follows the
'build' command if not set by the user.

to all commands in the same way.  Several Command methods now either expect
'self.force' to be defined, or check if it is defined and assume it's
false if not.

Added code to include source files from 'build_clib' command to default file
  list -- currently this won't work, since 'build_clib' doesn't have a
  'get_source_files()' method!

Python library hoping to find out more about the Distutils.

  - file_util.py: operations on single files
  - dir_util.py: operations on whole directories or directory trees
  - dep_util.py: simple timestamp-based dependency analysis
  - archive_util.py: creation of archive (tar, zip, ...) files
The functions left in util.py are miscellany that don't fit in any of the
new files.

the Command class from core.py to cmd.py.  No other code needs changing
though; distutils.core still provides the Command and Distribution classes,
although indirectly now.

functions, but with different names.

HKEY_* and Reg* names once, rather than having near-duplicate code
in the two import attempts.

Also dropped the leading underscore on all the imported symbols,
as it's not appropriate (they're not local to this module).

option to disable this (by default, it's false and we clean up).

we still have to *run* the sub-command that creates a built distribution.

multiple built distributions in one run -- it seemed a bit dodgy and I'd
rather remove it than try to beat it into submission right now.

Added 'ztar', 'tar' to 'format_command' dictionary.

eg. sunos5, linux2, irix5.

now done in the 'build_ext' command.

  * build to "Debug" or "Release" temp directory
  * put linker turds (.lib and .exp files) in the build temp directory
  * tack on "_d" to extensions built with debugging
  * added 'get_ext_libname()' help in putting linker turds to temp dir
Also, moved the code that simplifies None to empty list for a bunch
  of options to 'finalize_options()' instead of 'run()'.

specific to building Python extensions.

Simplified 'Command.get_peer_option()' a tad -- just call 'find_peer()'
  to get the peer command object.
Updated 'Command.copy_file()' to take a 'link' parameter, just like
  'util.copy_file()' does now.
Added 'Command.make_archive()' to wrap 'util.make_archive()'.

Changes to 'copy_file()':
  * added support for making hard links and symlinks
  * noted that it silently clobbers existing files when copying, but
    blows up if destination exists when linking -- hmmm...
  * error message tweak
Added 'base_name' parameter to 'make_tarball()' and 'make_zipfile()'.
Added 'make_archive()' -- wrapper around 'make_tarball()' or
  'make_zipfile()' to take care of the archive "root directory".

the command that actually creates "dumb" binary distributions, ie.
tarballs and zip files that you just unpack under <prefix> or <exec-prefix>.
Very limited, but it's a start.

Initial revision is pretty limited; it only knows how to generate "dumb"
binary distributions, i.e. a tarball on Unix and a zip file on Windows.
Also, due to limitations in the installation code, it only knows how to
distribute Python library code.  But hey, it's a start.
