Note that this one doesn't talk about cvs checkout at all,
but recommends different ways to get the RELEASE sources.

None of these is RELEASE.

If you want to understand what these two commands do, follow Nick's advice
and read FAQ 5.  Granted, that's not required for patching your system, but
maybe you want to understand what you are doing and why it fails...

Sometimes, it *is* useful to read a bit more than the bare minimum
required to type the right commands, in order to be able to understand
your own errors and become able to help yourself.

Yours,
