# A collection of useful functions related to git. This file must
# be sourced to bring its functions into the user path.

# delete_branches is a function, that once sourced, attempts to delete local
# and remote git branches from stdin or a file. The script
# prompts the user to delete each branch (local and remote).
#
# Example:
# $ git branch -r --sort=-committerdate | delete_branches
#
# To dos:
# * Check first if the same local branch exists, if not don't try to delete it.
# * Remember if you chose to skip deleting branch by creating a file and don't
#   ask the next time.
