1# Script to update the cached lexer and parser
2# Run after modifying lexer.lxx and/or parser.yxx
3#
4# 1. generate lexer and parser by building libminizinc
5# 2. run cmake -DPROJECT_SOURCE_DIR=. -DPROJECT_BINARY_DIR=build -P cmake/scripts/md5_gen.cmake
6# replacing . and build with the source and binary directory
7# add -DFORCE=ON to force the renewing of generated files when md5's still match.
