Regex Policy Daemon
The RegexPolicyDaemon (rxpd) can be used to efficiently check data against different lists of regular expressions. This can be used to build application defined lists to protect many kinds of Internet services. These lists can be distributed peer to peer between friends. Users can update, filter, and merge these distributed lists to create their own lists. It uses a simple textual protocol that is easy to implement in scripting languages. Example usages are access and content control (spam filtering) for CGI scripts, wikis, email, revision control systems, IRC servers and clients, and so on.

Changes: Some minor protocol changes. CLEAR removes all rules from a list now, and DELETE removes a list from the filesystem. Rule files are now automatically loaded when first referenced. Automatic saving of files (due SIGALRM or shutdown) saves only files that already exist on disk. Locking has been fixed and reworked. LIST only lists files that are allowed to be dumped. The rxpd xchat plugin is merged under ./contrib as an example application.

The Daemonizing code was rewritten. Signal handling was added to control the daemon.
