oggzdiff is a sh script which
uses oggzdump to generate hexadecimal packet dumps
of each input file, then outputs the difference between these dumps
using diff.
Options
oggzdiff forwards a subset of options
accepted by oggzdump and diff.
See
oggzdump(1) and
diff(1) for more detail.

Ogg bitstreams that differ only in serialno assignment.
"-G,
Hide the granulepos field of the preamble for
each packet dumped.
"-P,
Hide the packetno field of the preamble for
each packet dumped.

"-q,
Output only whether files differ.

"-u,
Output NUM (default 3) lines of unified context.
"-e,
