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.

C++ Resources Compiler is a tool that will generate a C++ source file (along with the corresponding header file) that embeds any given data file and provides a Resource class which gives access to this data. The Resource class can be created in two flavors: one using STL streams, the other using WxWidgets streams. Its function is similar to that of the "qtrc" tool from the Qt toolkit.
