"""\
Create a source tarball of a Python project from a (local) source tree.
All this command doing is packing up the source tree (ignoring .git,
.svn, .hg, *~, .pyc, etc... files), and giving the directory and the
tarball a good name (by calling setup.py --fullname). This may be
overwritten using the --dst option.
