Dosage is designed to keep a local copy of specific Web comics and other picture-based content such as Picture of the Day sites. With the dosage command line, script you can get the latest strip of a Web comic, catch up to the last strip downloaded, or download a strip for a particular date/index (if the comic's site layout makes this possible).
cfsm is a finite state machine compiler. It converts a high-level text description of a state machine into a C source and header file, and optionally a Graphviz dot graph. The generated code ensures that only explicitly permitted state transitions are possible, and supports optional precondition and transition callbacks.
