Synopsis

This script formats Python source code following the above style conventions.

frettipy [-f] FILE

If -f is present, FILE is modified in place! Keep a copy or use version control. Otherwise the intended modifications are shown without changing FILE.

If FILE is a directory, all .py and .Rmd files in the tree are processed!
