signatures, and updated some docstrings to reflect it.
Some comments added.
Added 'announce()' and 'move_file()' methods.

Error message tweak in Command.set_option().
Added Command.get_peer_option().
Added Command.move_file() wrapper.

        raise KeyError instead of failing silently!

much breakage (esp. in JPython which holds absolute path names in
co_filename already).  This implementation uses os.path.abspath() as a
slightly better way to canonicalize path names.  It implements a
cache.

the file that a function is defined on.  Non-portable to Windows and
JPython.  Instead, new find_function() uses re module on a similar
(simple-minded) pattern.

the proper function to call is inet_addr().  Since we already had code
to do that (for MS-Windows), this simplifies things a lot!

names match the documentation.

Removed broken code that supports the __methods__ attribute on ast
objects; the right magic was added to Py_FindMethod() since this was
originally written.  <ast-object>.__methods__ now works, so dir() and
rlcompleter are happy.

tracefunc (or profilefunc -- we're not sure which), zap the global
trace and profile funcs so that we can't get into recursive loop when
instantiating the resulting class based exception.

we no longer explicitly pull distribution options out of our Distribution
object, but rather let the Distribution put them into the command object.

  attributes, etc.  Biggest change was to the Distribution constructor
  -- it now looks for an 'options' attribute, which contains values
  (options) that are explicitly farmed out to the commands.  Also,
  certain options supplied to Distribution (ie. in the 'setup()' call in
  setup.py) are now "command option aliases", meaning they are dropped
  right into a certain command rather than being distribution options.
  This is handled by a new Distribution class attribute,
  'alias_options'.
Various comment changes to reflect the new way-of-thinking.
Added 'get_command_name()' method to Command -- was assuming its
  existence all along as 'command_name()', so changed the code that
  needs it to call 'get_command_name()'.

Ditched redundant '_gen_preprocess_options()' and '_gen_lib_options()'
  -- now provided by ccompiler.py.
Fixed some filename extension variables -- added missing period.
Cosmetic tweaks.

  now provided (minus the leading underscore) by the ccompiler module.
Fix 'compile()' to return the list of object files generated.
Cosmetic tweaks/delete cruft.

Added big comment about the kludginess of passing 'build_options'
  to the link methods and how to fix it.
Added 'gen_preprocess_options()' and 'gen_lib_options()' convenience
  functions -- the two cases are very similar for Unix C Compilers and
  VC++, so I figured I might as well unify the implementations.

Apparently os.name is "nt" or "posix" or we don't care.
Cosmetic tweaks.

dict.  Discovered by Christian Tismer.

for MSVCCompiler.

  - fix some broken abstract methods
  - kludge: add 'build_info' parameter to link methods
  - add 'object_name()' and 'shared_library_name()'
  - support for MSVCCompiler class on NT/Win95

(for Windows/CE).

(Suggested by Moshe Zadka, but implemented differently.)

Add <<python-docs>> event which, on Unix, brings up Netscape pointing
to http://www.python.doc/current/ (a local copy would be nice but its
location can't be predicted).  Windows solution TBD.

Add a new section describing what each of the tools does, in general
terms.
