-# This script takes the output produced from perly.y by byacc and
-# the perly.fixer shell script (i.e. the perly.c and perly.h built
-# for Unix systems) and patches them to produce copies containing
-# appropriate declarations for VMS handling of global symbols.
-#
-# If it finds that the input files are already patches for VMS,
-# it just copies the input to the output.
