Minimally Awesome Todos for Mac OS X

minimal_todo.sh

# Reference: http://blog.jerodsanto.net/2010/12/minimally-awesome-todos/
#
# Improvements:
#
# *) It now supports tracking multiple projects/todo files.
# *) Use 'cat -b' to get task order instead of hard-coding line number in files.
#
# 3 actions available:
# - Create a new task in project "prj": td prj task
# - Delete third task: tddone prj 3
# - Move third task on the top: tdtop pro 3
