swimitator is a tool for parsing swim-style workouts of the form:

500 SKIPS
2 x {
    4 x 50 K @1
    2 x 100 dr @1:45
}
10 x 100 K EN3 @1:30
...

The idea is to use PLY python lex/yacc to generate a small DSL representing the kind of notation you might use to input a workout. The output will be tailored toward entering in a database containing information about workouts and sets in order to track swimming workout information.
