>Description:
         /usr/bin/cvs diff --side-by-side --width=183 --expand-tabs

  returns:

cvs server: invalid option -- y
Usage: cvs server [-lNR] [rcsdiff-options]
    [[-r rev1 | -D date1] [-r rev2 | -D date2]] [files...] 
        -l      Local directory only, not recursive
        -R      Process directories recursively.
        -D d1   Diff revision for date against working file.
        -D d2   Diff rev1/date1 against date2.
        -N      include diffs for added and removed files.
        -r rev1 Diff revision for rev1 against working file.
        -r rev2 Diff rev1/date1 against rev2.
        --ifdef=arg     Output diffs in ifdef format.
(consult the documentation for your diff program for rcsdiff-options.
The most popular is -c for context diffs but there are many more).
(Specify the --help global option for a list of other help options)

>How-To-Repeat:
        run 'cvs diff --side-by-side'
>Fix:
        It occurs to me as I write this, that this might be because
        our CVS server is running 1.10.7 and the client is `1.11.1p1.
        If this is the case, it should at least be documented somewhere.
