exists before calling the compiler/linker.

the compiler objects 'verbose' and 'dry_run' flags.

'Distribution.find_command_obj()'.

platform, using 'os.uname()' or 'sys.platform'.

  * '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

  * 'build_lib' -> 'build_purelib'
  * new 'build_lib' and 'build_temp' options
  * use 'get_platform()' to initialize 'build_platlib' and 'build_temp'

cooked up by Fred Drake and me.  Only saved for posterity (whoever posterity
is), as it is about to be ditched in favour of GvR's much simpler design.

'set_final_options()' to 'initialize_options()' and 'finalize_options()'.

'set_final_options()' to 'finalize_options()'.

Unrelated comment changes.

in 'find_command_class()' method.

command itself: no more of this "FooBar class for foo_bar command"
silliness.

old 'dist' command, but the code for dealing with manifests is completely
redone -- and renaming the command to 'sdist' is more symmetric with the
soon-to-exist 'bdist' command.

  'get_msvc_paths()'.
Renamed '_do_SET()' to 'set_path_env_var()', tweaked docstring, and
  cosmetically tweaked code.
Stylistic changes to MSVCCompiler constructor (variable renaming
  and type consistency).

  * tweak my docstrings
  * fix None returns to empty list
  * reshuffle responsibilities between '_find_exe()', '_find_SET()', and
    the MSVCCompiler constructor -- now the constructor worries about
    fetching the version list and determining the most recent one
  * added "/W3" compile option
Also, I added/tweaked some docstrings.

function names, dbetter (hopefully) ocstrings, and comments.

/export option mini-kludge.

  * don't need to mention python<ver>.lib -- it's done by a pragma
  * add debug flags for compile and link, and use them
  * fix 'link_shared_library()' to pass everything to 'link_shared_object()'
  * change filename when shared object with debug info (ugh)

to fallback to if the user doesn't set it for those commands.

  someone who knows Windows/MSVC++ to come along and add the right flags.
Comment noting that 'link_static_lib()' signature is inconsistent with
  the other compiler classes (uh-oh!)

'-g' flag to compiler/linker command lines when it's true.

Doc fix: several paragraphs under 'link_static_lib()' moved to
  'link_shared_lib()', where they belong.

_init_nt():  Use get_config_h_filename() instead of figuring out the
             name directly.

             g['SO'] should be set to '.pyd'.

             Adjust some minor coding nits.

harder to find the MSVC compiler (mainly by using the registry).

Typo fix.

in the current distribution: motivated by PIL's libImaging.

Announce when we start building each extension (better feedback).

feedback and, theoretically, the opportunity to set compiler flags
on a per-file basis.
