NAME
       fragiso - split rpm packages from an iso and reassemble the iso later on

SYNOPSIS
       fragiso make iso fiso
       fragiso list fiso
       fragiso fill [-m] fiso iso

DESCRIPTION
       fragiso	can  be  used  to convert an iso file into a fragment file, which is a list describing all of the rpms on the iso and a data chunk
       containing everything but the rpms. It is used by drpmsync when an iso needs to be transferred. The idea is that often the rpms on the  iso
       are already available on the destination host, so it saves bandwidth to first transfer the fragmented iso, copy the locally available rpms,
       transfer the unavailable rpms and reassemble the iso file.

       fragiso make converts the iso into the fragment iso, fragiso list can be used to extract the rpm information. This information consists	of
       the  offset  and  length  of all rpms and the lead/signature header md5sum plus the header/payload md5sum. To reassemble the iso one has to
       copy the rpms at the right offset into a new file and then use fragiso fill later on to provide all data not contained in the rpms. The	-m
       option tells fragiso to print the resulting md5sum of the iso to stdout.  It can be used for verification purposes.
