Note that allowing dots may now cause problems for projects with '.' in
the name that were previously installed, since such projects had to be
spelled with a '-' before.  The '-' name will no longer match the '.'
project, and there is no real room for backward compatibility here.  :(

format.  Running ``bdist_wininst`` on a setuptools-based package wraps the
egg in an .exe that will safely install it as an egg (i.e., with metadata
and entry-point wrapper scripts), and ``easy_install`` can turn the .exe
back into an ``.egg`` file or directory and install it as such.

At this point, it should also be possible to "system package" any egg,
complete with wrapper scripts, and at least bdist_wininst works now.
More testing is needed for at least bdist_dumb and bdist_rpm.

command so that you can more easily wrap a "flat" egg in a system package.
Enhanced ``bdist_rpm`` so that it installs single-version eggs that
don't rely on a ``.pth`` file.  The ``--no-egg`` option has been removed,
since all RPMs are now built in a more backwards-compatible format.

Some work is now needed for easy_install to recognize bdist_wininst
.exe's that wrap these new flat eggs, as currently the .egg-info will
not be recognized.

that ``0.2-rc1`` is considered an *older* version than ``0.2``, and is equal
to ``0.2rc1``.  The idea that a dash *always* meant a post-release version
was highly non-intuitive to setuptools users and Python developers, who
seem to want to use ``-rc`` version numbers a lot.
