* replaced build_lib.py with build_clib.py
* renamed the class in build_clib.py
* changed all references to 'build_lib' command in other command classes
when building extensions (uses build_lib's 'get_library_names()' method).
Ensure that the relative structure of source filenames is preserved in
the temporary build tree, eg. foo/bar.c compiles to
build/temp.<plat>/foo/bar.o.
* 'build_dir' -> 'build_lib', which by default takes its value
straight from 'build_lib' in the 'build' command
* added 'build_temp' and 'inplace' options
* change 'build_extensions()' to put object files (compiler turds) in
'build_temp' dir
* complicated the name-of-extension-file shenanigans in
'build_extensions()' to support "in-place" extension building, i.e.
put the extension right into the source tree (handy for developers)
* added 'get_ext_fullname()', renamed 'extension_filename()' to
'get_ext_filename()', and tweaked the latter a bit -- all to support
the new filename shenanigans
'--help-commands' option).
Shuffled imports around in a few command modules to avoid expensive
up-front import of sysconfig (and resulting delays in generating list
of all commands).
Catch up with renamed 'platdir' -> 'build_platlib' option in 'build'.
Don't call 'set_final_options()' in 'run()' anymore -- that's now
guaranteed to be taken care of for us by the Distribution instance.
If 'include_dirs' is a string, split it on os.pathsep (this is half-
hearted -- support for setting compile/link options on the command
line is totally lame and probably won't work at all).
Added 'get_source_files()' for use by 'dist' command.
Added code to 'build_extensions()' to figure out the "def file" to use
with MSVC++ and add it to the linker command line as an "extra_postarg".
- rename 'dir' to 'build_dir'
- take 'package' from distribution option 'ext_package'
- take 'extensions' from distribution option 'ext_modules'
- take 'include_dirs' from distribution
Name keyword args explictly when calling CCompiler methods.
Overhauled how we generate extension filenames (in 'extension_filename()
and 'build_extension()') to take 'package' option into account.
