Currently to run any of the scripts, the user needs to clone the git repo. This is not a very nice method for python projects, as pip is the defacto for installing python packages.
It would be nice to make a pywikibot-scripts pypi packages which installs all pywikibot scripts. This way, for a user to install and run pywikibot's official scripts, all they'd have to do is:
$ pip install pywikibot-scripts $ pwb <script name to run>
Note: The pwb command is described at https://phabricator.wikimedia.org/T139143
