# Source this and then run `todo`

# a simple way to manage your todo list
# Usage:
#  todo                    -- pull latest repo version and edit ~/todo
#  todo [any git command]  -- manage todo for easy syncing, assuming ~/todo is
#                                a symlink that points to a file in a git repo
#
# Suggested use: make a git repo for holding your todo list, then make
# a symlink called 'todo' that points to your todo list in your home directory
#
