# This script is used to take a goldsrc-style character model with the origin at
# its centerpoint and put its origin at its feet.
#
# It parses a .qc file, takes all $origin commands, and subtracts that amount
# from all 'origin' blocks inside a sequence command.
#
# Redirect its output to a file (or the input file).
