requires and provides. requires is a sequence of strings, of the
form 'packagename-version'. The dependency checking so far merely
does an '__import__(packagename)' and checks for packagename.__version__
You can also leave off the version, and any version of the package
will be installed.
There's a special case for the package 'python' - sys.version_info
is used, so
requires= ( 'python-2.3', )
just works.
Provides is of the same format as requires - but if it's not supplied,
a provides is generated by adding the version to each entry in packages,
or modules if packages isn't there.
Provides is currently only used in the PKG-INFO file. Shortly, PyPI
will grow the ability to accept these lines, and register will be
updated to send them.
There's a new command 'checkdep' command that runs these checks.
For this version, only greater-than-or-equal checking is done. We'll
add the ability to specify an optional operator later.

"While attempting to build an RPM using distutils on Python 2.0,
rpm complained about duplicate files. The following patch fixed
that problem.
'convert_paths()' method to convert them all to the local syntax (backslash
or colon or whatever) at the appropriate time.
Added SCHEME_KEYS to get rid of one hard-coded list of attributes (in
'select_scheme()').
Default 'install_path_file' to true, and never set it false (it's just
there in case some outsider somewhere wants to disable installation of the
.pth file for whatever reason).
Toned down the warning emitted when 'install_path_file' is false, since we
no longer know why it might be false.
Added 'warn_dir' flag to suppress warning when installing to a directory
not in sys.path (again, we never set this false -- it's there for outsiders
to use, specifically the "bdist_*" commands).
Pulled the loop of 'change_root()' calls out to new method 'change_roots()'.
Comment updates/deletions/additions.
of globals from sysconfig.
Added 'prefix' and 'exec_prefix' to the list of variables that can be
expanded in installation directories (preserving the stupid old names
of 'sys_prefix' and 'sys_exec_prefix, though).
participates in the "--root" hack, ie. it also has a new root directory
hacked on at the very last minute (essential if the .pth file is to be
included in an RPM or other smart installer!).
the "install_data" command to the installation base, which is usually just
sys.prefix. (Any setup scripts out there that specify data files will have
to set the installation directory, relative to the base, explicitly.)
* Command method 'find_peer()' -> 'get_finalized_command()'
* Command method 'run_peer()' -> 'run_command()'
Also deleted the 'get_command_option()' method from Command, and
fixed the one place where it was used (in "bdist_dumb").
* 'headers' entry added to all the install schemes
* '--install-headers' option added
* 'install_headers' added to 'sub_commands'
* added 'dist_name' to configuration variables (along with a few
others that seem handy: 'dist_version', 'dist_fullname', and
'py_version'
* in 'finalize_unix()', make sure 'install_headers' defined if
user specified 'install_base' and/or 'install_platbase'
* added 'has_headers()'
* a few other small changes
objects, it now has method names.
Added three methods, 'has_lib()', 'has_scripts()', and 'has_data()'
to determine if we need to run each of the three possible sub-commands.
Added 'get_sub_commands()' to take care of finding the methods named
in 'sub_commands', running them, and interpreting the results to
build a list of sub-commands that actually have to be run.
adds the 'install_data' and 'install_scripts' commands; these two
are trivial thanks to the 'install_misc' base class in cmd.py.
(Minor tweaks and commentary by me; the code is untested so far.)
