Re: Protect CVSROOT tree

[Howard Zhou]

Dale,

CVSROOT $CVSROOT/CVSROOT/commitinfo_ckuser -user=$USER

Do you put the trigger script in $CVSROOT but not commited? Just curious. I
don't see how -user=$USER works here.
Does this script apply to CVSROOT module only?

What is the checkoutlist mentioned below?
