Ivy is a simple protocol and a set of libraries that allows applications to broadcast information
through text messages, with a subscription mechanism based on regular expressions.

This version includes better regular expression error-handling. The ivy-perl lib now warns whenever a message containing a \n is sent. New features include the ability to know every regexp subscribed / unsubscribed by other agents with statusfunc, and ivyprobe.pl now displays all subscriptions / unsubscriptions and also allows unsubscriptions. Minor bugs have also been corrected.
