# This helper script makes it easy to use a passwd or group file to map
# values in a LOCAL transfer.  For instance, if you mount a backup that
# does not have the same passwd setup as the local machine, you can do
# a copy FROM the backup area as follows and get the differing ID values
# mapped just like a remote transfer FROM the backed-up machine would do:
#
# rsync -av --usermap=`mapfrom /mnt/backup/etc/passwd` \
#           --groupmap=`mapfrom /mnt/backup/etc/group` \
#           /mnt/backup/some/src/ /some/dest/
