Scribbler is a quick, easy, minimalistic diary script written in Python. When called without arguments, it allows you to edit today's diary entry. When the -b option is used, it allows you to browse old diary entries. Scribbler uses vim and lynx by default, but you can easily change these settings to your favorite editor/browser.
