+.TH UUDIFF 1C 
+.SH NAME
+uudiff \- directory comparison between machines
+.SH SYNOPSIS
+.B uudiff
+[ \-d ]
+local-name remote-name
+.SH DESCRIPTION
+.I Uudiff
+compares the files in the directory
+.I local-name
+and the directory
+.I remote-name,
+(where
+.I remote-name
+may be of the form
+.I system-name!directory-name
+and
+.I system-name
+is a 
+.I uucp
+Unix name).
+It reports (via mail)
+which files are added, deleted, or changed, and provides
+a
+.I diff(1)
+of altered printable files.
+.PP
+If a part of
+.I remote-name
+is omitted
+(either the system or the directory)
+the corresponding part of
+.I local-name
+is used.
+If
+.I local-name
+is a file, rather than a directory,
+.I remote-name
+is also assumed to be a file and the program degenerates into
+.IR diff(1) .
+.PP
+The option
+.B \-d
+does not diff altered files; only
+the summary by file names is prepared.
+.SH FILES
+Lots.  Files zz[abcdeglmn]????? are used for scratch space;
+files brought back from the remote machine for
+.I diffing
+are stored (and left around) as
+.I name.?????
+and the final report is left in
+.I uudiff.?????
+(the exact name is reported by mail).
+.SH "SEE ALSO"
+diff(1), uucp(1)
+.SH DIAGNOSTICS
+Almost none.  Anything more serious than misspelling
+.I local-name
+causes unpredictable and obscure results.
+.SH BUGS
+In addition to the standard
+.I uucp
+requirements a hook is needed at the remote
+system, and at present is only installed
+on the systems "research" and "inter".
+.br
+This program is written in shell and should be translated
+to C so it could give diagnostics.
+.br
+Even if "remote-system" is the local system, uudiff
+is subject to delays in uucp traffic.
+.br
+It should probably write the standard output, instead of insisting
+on going into the background.
+.br
+Since checksums are used there is a probability of 1 in 2**32
+of missing differences between files.
+.br
+The ~userid syntax is not recognized.
