The commitinfo triggered script may run a command like 'cvs -n status'
on the list of files and you could parse that looking for any 'dead'
'Sticky Tag:' entry. Another possibility is to actually read the
CVS/Entries file looking for the files that are being tested and
reject commits that deal in the branch you consider dead.

This is a perl fragment that can read a CVS/Entries file:

$ENTRIES = 'CVS/Entries';
open(ENTRIES, $ENTRIES) || die("Cannot open $ENTRIES.\n");
while (<ENTRIES>) {
    chomp;
    # /file/ver/timestamp/options/tag_or_date
    my($filename, $version,$ts,$opt,$tag) = split('/', substr($_, 1));
    $cvsversion{$filename} = $version;
    if ($tag =~ /^T/) {
        $tag =~ s,^T,-r,;               #  tag indication
    }
    if ($tag eq '' || $tag =~ /^-r/) {
        $cvsbranch{$filename} = $tag;
    }
    $cvsoption{$filename} = $opt;
}
close(ENTRIES);


the $cvsbranch{$filename} will contain a -rTAG or '' value that was
given by the user on checkout or update of their tree, so you could
compare it against the list of -rdead-branch values you want to use.

        Good luck,
