## git-mv-new-repo
# Instructions how to transfer several directories from one repo to another
# while preserving the history

git clone <git dest> dest
git clone <git src> src

# Prepare the source repo
cd src
git checkout <branch from where to copy the direcoties>

## git-mv-with-history
#!/bin/bash
#
# git-mv-with-history -- move/rename file or folder, with history.
#
# Moving a file in git doesn't track history, so the purpose of this
# utility is best explained from the kernel wiki:
#
#   Git has a rename command git mv, but that is just for convenience.
#   The effect is indistinguishable from removing the file and adding another
#   with different name and the same content.
