Git Archive Bash Script

gitarchive.sh

# Takes one parameter: a remote git repository URL.
#
# This is the stuff this script does:
#
# 1. Clones the repository
# 2. Fetches all remote branches
# 3. Compresses the folder
# 4. Deletes the cloned folder.
#
# Your remote repository is left untouched by this script.
