Simple external score parser for Angband.

scores.py

#!/usr/bin/python
#
# by Erik Osheim
#
# External score parser/printer for Angband. It hardcores some
# values from p_races.txt and classes.txt for simplicitly.
# Should basically mimic the built-in format.
#
# One caveat: does not currently display the current (living)
# character, since this character's information is not in the
# score file.
#
# Seems to work as of 2014-07-04 (1aba7a8).
