Crap, this script was added with the following problems ...
1. called contacts package (fixed previously) 2. embedded PG-only queries (no xql files, no attempt to make this dotlrn component work with oracle despite our policy of supporting oracle) 3. authorship misattributed to tracy adams (copied another script as a stub), she wasn't the source of these problems
Malte FUCKING called his contacts package from the notifications packages, causing it to break. Of course there was no requires tag in the info file so it didn't break until you actually tried using a package that uses notifications.
And even better, there's already a proc in acs-tcl/tcl - an ancient one - that does the same thing anyway.
