# This tools is kind of a hack to be able to maintain the credits list of
# ScummVM in a single central location. We then generate the various versions
# of the credits in other places from this source. In particular:
# - The AUTHORS file
# - The gui/credits.h header file
# - The credits.xml file, part of the DocBook manual
# - Finally, credits.inc, from the website
# And maybe in the future, also "doc/10.tex", the LaTeX version of the README.
# Although that might soon be obsolete, if the manual evolves enough.
#
# Initial version written by Fingolfin in December 2004.
