.SH DESCRIPTION
.B xzcmp
and

are used to invoke the
.BR cmp (1)
or the
.BR diff (1)
program on compressed files. All options specified are passed directly to
.B cmp
or
.BR diff "."
If only 1 file is specified, then the files compared are
.I file1
(which must have .xz or .lzma suffix) and
.I file1
from which the .xz or .lzma suffix has been stripped.
If two files are specified, then they are uncompressed if necessary and fed to
.B cmp
or
.BR diff "."
The exit status from
.B cmp
or
.B diff
is preserved.
