####################### INSTALLATION AND USAGE #######################
#
#
# Place todo.sh in your PATH so you can easily run it. Make sure you
# set permissions to write and read.
# You can easily add a task with:
#		todo -a "Task goes here"
# You can easily view tasks with:
# 		todo -l simple 		(shows a numbered list)
#		todo -l full 			(shows when task is created)
# NOTE: Theres no way to delete tasks yet.


## Changelog
# TODOFORMAT needs a way to check the last line and number to add a task # greater than the prev-
# ious line. (MAYBE NOT -.-)

# to be implemented with Priority colors
