My solutions to ACM Uva contest problems.

Includes a helper script, uvatool.py. Usage:

$ alias u='python uvatool.py'

Show a problem description (downloads and caches to disk).

$ u view 424 --text

Edit the problem (stores the expected input and output as comments in the beginning of the file)

$ u edit 424

Test the program against expected input-output in the source file.

$ u test 424
PASS

$ u test 10920
