-# This .ini file extracts grammars to a file using

-# Does not do any decoding.
-#
-# Variables can be set using sa-system.pl
-#
-# Usage: decoder.py -c <this ini file> [-x <grammar file>]
-#
-# If the -x option is used, grammar will be written to the
-# specified file, otherwise it is written to $PWD/grammar.out
-#
-# NOTE: all information about rules is cached, so use generous
-# memory limits (rules themselves are not cached.)
