* doc/gzip.texi (Overview): Update RFC URLs. * gzip.1: Likewise. Don't say "SEE ALSO" to programs that almost nobody has installed anymore. * gzip.1, zmore.1: Fix some troff typos. * zdiff.1: Clarify what happens with input files. Don't talk about temporary file names, as they're rarely used these days.

.SH DESCRIPTION
|
|
.I Zcmp
|
|
and
|
|
.I zdiff
|
|
are used to invoke the
|
|
.I cmp
|
|
or the
|
|
.I diff
|
|
program on files compressed via
|
|
.IR gzip "."
|
|
All options specified are passed directly to
|
|
.I cmp
|
|
or
|
|
.IR diff "."
|
|
If only
|
|
.I file1
|
|
is specified, it is compared to the uncompressed contents of
|
|
.IR file1 ".gz."
|
|
If two files are specified, their contents (uncompressed if necessary) are fed to
|
|
.I cmp
|
|
or
|
|
.IR diff "."
|
|
The input files are not modified.
|
|
The exit status from
|
|
.I cmp
|
|
or
|
|
.I diff
|
|
is preserved.
|
|
.SH "SEE ALSO"

|
Messages from the
|
|
.I cmp
|
|
or
|
|
.I diff
|
|
programs may refer to file names such as "\-" instead of to the file
|
|
names specified.
