#
# 1. Create a new verification_info.cmake file and populate
# it with the current versions of perplex, re2c and lemon.
# Also add the MD5 sums for current template files.
#
# 2. For all files that need to be updated in the cache,
# calculate new MD5 sums and add them to the new
# verification_info.cmake - this is usually the input
# files and the generated outputs.

# and generated files with the new ones. If LOCKED_SOURCE_DIR
# is ON, this step will not be carried out - instead, an
# informational message with manual updating instructions
