This week I discovered a useful little command line application to process my todo list. Todo.txt processes a plain text file and allows you to maintain the list with a few command line calls. Because the file is in plain text I can just print it out if I am going to be away from my system.
Trying to describe how flexible it is isn't easy. It really is something you need to try out yourself. Give Todo.txt a shot, you could get addicted to it like me.
