I agree, and I also support Jonathan Shapiro's idea that a
cvs-compatibility wrapper could be written in Perl and would simply
map the CVS options to the Subversion options (and maybe echo the
proper 'svn' options back so that it'd serve as a learning tool as
well.)

That way, Subversion can have its own options (-r instead of -R)
and not have to worry about the CVS cruft like '-d' meaning one
thing as a global option and another thing as a command option.
