### BASH Todo v.01
### A Super Simple Todo CLI
### Created by: Lazy

######################################################################
####################### 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)
#


## Changelog
# 	-TODOFORMAT removed. Task numberer finished. (For some reason the function
# 	doesn't manipulate TODO file (WHY?) )
