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

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