This commit fixes a couple of things:
* Removes the command line argument called release_version, now
one doesn't have to supply a version number when running just
running --cleanup, for instance.
* Run --cleanup before building the wheels and sdists. This is so
that outdated distributions are removed before generating new
ones.
* Set IS_PYPA_PACKAGE back to False at the end of the --build
process so that we don't accidentally set it to True. This was
a huge bug in the previous version of the script.
This commit adds a script to automate the PyPA release of the
zulip, zulip_bots and zulip_botserver packages.
The tools/release-packages script would take care of uploading
the packages to PyPA, and push commits to both repos updating the
package versions. If you have commit access to the repos, you
can --push upstream to master. If not, then you can --push
origin to a new branch on your fork and create a PR for those
changes.
Ideally, a release shouldn't take longer than however long it
takes one to type the above command. If you have SSH set up on
GitHub, you won't need to type in your GitHub username and
password. You can also store your PyPA credentials in a file
in your home directory; it isn't very secure, but it saves
time nevertheless.
