# GIT Repository update script by Sebastian Teumert | |
# | |
# Stashes local changes, checks out specified branch, pulls branch from origin | |
# and pushes to upstream. | |
# | |
# Used to keep forks synced with their origin | |
# | |
# When no argument is specified, this script works in pwd, works on the 'master'- | |
# branch and uses the git remote 'origin' to pull and 'upstream' to push | |
# help message | |
