I was poking around with the -s option for cvs and I didn't see support
for it in the netbeans cvs client.  This is a very powerful option that
we use here for governing whether a cvs commit should launch the build
and deploy mechanism.

for example,

cvs -s DEPLOY=yes commit -m "added new widget to visualize whirled peas"

would substitute the DEPLOY variable in the loginfo script and lock the commits,
build it, and then deploy the system.

you can also leverage it off the taginfo script to do the following.

cvs -n -s DEPLOY=yes tag nonsense 

which could do the same thing, but not actually perform the tag operation.  The
commit operation requires a file to have changed, even for the -n...but tag has
no such restrictions.  Another thing you could do (with the cvs server that is)
would be to do -s ANT=target to have it launch a particular ant target.

Very powerful mechanism for cvs.
