[Whole message included for context.]
It's a bit more complicated than that though isn't it? The Template
file doesn't exist locally as such. There's a mechanism in that selects
the correct template to use depending upon in which directory the change
is being made. The CVSROOT/rcsinfo file contains regular expressions
and the name of the file to be used as the Template. In our case we've
got a single entry:
ALL $CVSROOT/CVSROOT/rcstemplate
This means that rcstemplate gets used universally as the Template within
our repository, but in general this isn't the case.
Can you think of a work around for this too?
Joe
