In order to disable modifying tag contents after the tag has been marked, the following script should be installed as $SVN_REPO/hooks/pre-commit


#!/usr/bin/perl


my $repo = ${ARGV[0]};
my $tx = ${ARGV[1]};
my $changed = qx{/usr/local/bin/svnlook changed -t $tx $repo};


die «Rejecting commit under tag: \n$changed»

if $changed =~ /^[UA].+?\/tags\/[\w-]+\/.+$/g

;
