# This script takes a file mapping CSV file as input (see Flist.csv for an
# example) and outputs a ksh script containing the SCCS and Teamware commands
# necessary to merge the required files from a stock perl 5.6.1 build directory
# on top of a workspace containing the existing 5.005_03 version.  Note that
# the 'sleep 1' commands are because Teamware can't cope with rapid check-ins
# of large numbers of files.
