The \fBrpmdiff\fR(1) command compares the contents of the files contained within the
rpms \fIfrom-rpm\fR and \fIto-rpm\fR.

and \fBcpio\fR(1L).

\fIdiffoptions\fR are the options which will be passed
to \fBdiff\fR after extracting the files from the rpms.  If no \fIdiffoptions\fR
are supplied the default of \fI-uNr\fR will be used.
