$ todo
Run the script with no options, and you will be prompted to enter
a tag; a date; and a message
all on one line, separated by semi-colons. Spaces don't matter, but be consistent about whether you use a space before and after the semi-colon, so your fields line up when you recall them. Nothing needs to be quoted. It is now safe to use colons in the message field. (starting with version .04.1)
Examples:
admin; fri ; run the backups
hobby; 2011-01-12; poker with Ian 08:00 pm
family; next fri; birthday uncle Charly
After you enter the item, you are presented with the entry screen again. To exit this screen hit the enter key without typing anything.
