 What is the tag for release 21.1? 
It is the default branch.  If you `cvs update' a 21.0 source tree, you 
will get pre-21.1.1.  If you `cvs checkout' without specifying a
release, you should get the right stuff.
 The CVS command checkout -rr21-1-1 didn't work, but -r21-1-0
fetched
 a bunch of stuff.  Did I get the right stuff? 
No.  The tag `r21-1-0' is a placeholder so that when the release
scripts for 21.1.1 are run, the patch kits will be built correctly.
It is identical to 21.0.67.
