 # Easy, quick & dirty solution to act upon multiple git repositories at once.

-# TODO:
-#   - use 'gitpython' instead of calling `git`?
+#
+# Implementation:
+# - Wrap around the existing `git` command instead of using the 'gitpython' library to allow for aliases.
+# - Use the 'click' libraries for CLI arguments for ease of use.
+#
+# Improvements:
+# - Use multiprocessing instead of multithreading?
