# A simple helper script for using ASCII todo lists
# The basic implementation knows 3 different states
# [ ] To Do
# [x] Done
# [o] Currently not possible to do
#
# The script is able to toggle between this states. If 
# you want only two states or if you want more states
# just edit the checkboxes string list.
#
# If a line doesn't contain a checkbox the script
# just inserts one at the current position.
