Asking CVS if a repository/module/tag exists.

[John Daniel Doucette]

Hi,

Given a <repository>, <module>, and <tag> is there a polite way to ask CVS 
if the combination exists, without actually checking it out, that would 
work in a make file.  I.e. the command should fail if one of the three 
supplied parameters are incorrect, but succeed otherwise.  Currently I am 
using this construct in a make file, which works, but seems rather brutish.

cvs -d <repository> -r checkout -p -r <tag>  <module>


If the repository/tag/module is wrong it does fail, but if it is ok you get 
a large amount of stuff spewed to the screen.   Redirecting outout to a 
file helps a bit. I couldn't find anything appropriate in cvs status or cvs 
log.
