co-author commits

#!/bin/bash

# How to use this little dev tool
#
# You need to add the following snippet to .git/config
# [commit]
#    template = .git/.gitmessage
#
# And this is how you should run it
# ./pair-with.sh will simply empty the .gitmessage file
# ./pair-with DM will create this content:
#   Co-authored-by: Daniel Moor <[email protected]>

# It is also possible to add multiple developers as co authors at the same time:
# ./pair-with XY AB MN
