they make sure that 'set_final_options()' has been called, but isn't
  called redundantly.
Changed Distribution to call 'ensure_ready()' where it used to call
  'set_final_options()', and in a few extra places as well.
Lots of comment/docstring revisions and additions in both classes.
New one-liner utility methods in Command: 'find_peer()', 'spawn()'.

Job.warning():  New method; use this instead of writing to sys.stderr

Some code to help suppress various navigational pages; this might be
interesting when generating HTML to create HTML Help documents, since
the navigation support creates confusing hits in the full text
search.  HTML Help also provides a lot of the navigational
infrastructure, so duplicating it makes it more tedious to use.

It's possible to get a sunaudiodev.error (errno == EINVAL), although
I'm not exactly sure why, this at least won't crash the application.

  'alias_options' table and getting rid of some hairy code in the
  Distribution constructor.
Resurrected the distribution options that describe the modules present
  in the module distribution ('py_modules', 'ext_modules'), and added
  a bunch more: 'packages', 'package_dir', 'ext_package', 'include_dirs',
  'install_path'.
Updated some comments.
Added 'warn()' method to Command.
'Command.get_command_name()' now stores generated command name in
  self.command_name.

Added global cache PATH_CREATED used by 'mkpath()' to ensure it doesn't
  try to create the same path more than once in a session (and, more
  importantly, to ensure that it doesn't print "creating X" more than
  once for each X per session!).

  distributions their own directory (and .pth file).
Overhauled how we determine installation directories in
  'set_final_options()' to separate platform-dependence and take
  'install_path' option into account.
Added 'create_path_file()' to create path config file when 'install_path'
  given.
Only run 'install_py' and 'install_ext' when, respectively, there are
  some pure Python modules and some extension modules in the distribution.

Overhauled how we generate extension filenames (in 'extension_filename()
