# This script takes a file mapping CSV file as input (see Flist.csv for an
# example) and copies all the changed files from a stock perl build directory
# into an ON workspace. If you are patching perl, make sure to run
# 'ConfigPerl; make regen_headers; make; make test' before running this script.
# Note also that if the patches include new files they will NOT be dealt with
# correctly by this script - you should update fhe Flist.csv file and copy the
# files across manually. Also, it will be necessary to manually generate and
# check in the appropriate config.h file for other architectures.
