# There are two optional arguments:
#
# 1. directory that contains the grammar implementation
# 2. file list pattern (must be in quotes),
#    referencing the vocabulary files in multiple languages
#
# Usage examples:
#
# bash make-pgf.bash grammars/acewiki_aceowl/ "words/ontograph_40/TestAttempto{Ace,}.gf"

# ACE RG files
ace="lib/src/ace/"
api="lib/src/api/"
