An extensible library for opening URLs using a variety protocols.
Intended as a replacement for urllib.

isinstance(x, types.CodeType).

Suggested by Finn Bock.

Made all textfields in message and question boxes minimal height and invisible, and use AutoSizeDialog() and ShowWindow() before doing interaction.

Tweaked error messages in '_spawn_posix()'.

RT library.

Fixed 'make_release_tree()' to copy files if 'os.link()' doesn't exist.

before storing or using.

ParsedDate didn't have the correct day of week.

Herborth, the code in list2set() that sets max unconditionally to 0
should not be used on BeOS.  So be it.  Anybody using BeOS, please
test!

- Fixed StandardPutFile: prompt, default
- Check explicitly for userCanceledErr, pass other Nav.error exceptions through.

Python object freeing.

PR#175 -- when exec is passed a code object, it didn't sync the locals
from the dictionary back into their fast representation.

Also took the time to remove some repetitive code there and to do the
syncing even when an exception is raised (since a partial effect
should still be synced).

only.  Through some mysterious interaction, they would take 9 separate
arguments as well.  This misfeature is now disabled (to end a

previous output.  Call clearerr() to prevent past errors affecting our
ferror() test later, in PyObject_Print().  Suggested by Marc Lemburg.

the 'missing' parameter.

Added 'link_static_lib()' method, and 'archiver' and 'archiver_options'
  class attributes to support it.
Added 'link_executable()' method, and 'ld_exec' instance attribute
  to support it.
'newer_group()' is now able to handle missing files, so we don't have
  to kludge it by catching OSError when calling it.
'object_filenames()' and 'shared_object_filename()' now take 'keep_dir'
  flag parameters.
'library_filename()' and 'shared_library_filename()' now respect
  a directory component in the library name.
Various comment updates/deletions.

Added 'link_executable()' signature.

Added initializer routine optionally to be used as PEF fragment initialization routine, which allows us to get at our own resource fork even if some shared library init routine opens other resource files.

        constants when using the *conf*() APIs.
