Quickly rewrite git repository history

 git filter-repo is a versatile tool for rewriting history, which includes
 capabilities not found anywhere else. It roughly falls into the
 same space of tool as git filter-branch but without the capitulation-inducing
 poor performance, with far more capabilities, and with a design that scales
 usability-wise beyond trivial rewriting cases. git filter-repo is now
 recommended by the git project instead of git filter-branch.
 .
 While most users will probably just use filter-repo as a simple command
 line tool (and likely only use a few of its flags), at its core filter-repo
 contains a library for creating history rewriting tools. As such, users
 with specialized needs can leverage it to quickly create entirely new
 history rewriting tools.
