my "keep" script

[snippsat]

now, what would be useful would be a tool that keeps files i edit in a local copy and in a version control repository in a way where i won't need to do anything more, along with a grep tool that can grep the entire history of that file.  even better if such a tool can support GIT, HG, and SVN.

This is exactly what GitHub,Bitbucket does,that is powered bye Git.

The way you share your keep.py now is a uncommon way(you have or own way for most thing),
and i guess very few or no one will use it.

There is a standard to share stuff in Python,
is usually GitHub,BitBucket Repo in combination with PyPi for medium to large project, 
smaller project can just be PyPi alone or just share in Forum like this for small scripts. 

A good example(TextBlob) how this can be done for a medium size package:
TextBlob doc, TextBlob GitHub Repo and TextBlob PyPi Repo that also has wheel.
