dkimproxy is an SMTP proxy that signs and/or verifies Domain Keys Identified Mail (DKIM). It is designed to work with Postfix. It comprises two separate proxies: an "outbound" proxy for signing outgoing email, and an "inbound" proxy for verifying signatures of incoming email. With Postfix, the proxies can operate as either Before-Queue or After-Queue content filters.
The CentralNic Toolkit is CentralNic's system for instantaneous Registry-Registrar Communications.

Search::Xapian is a Perl XS frontend to the Xapian C++ search library. It is a fairly complete wrapper: most features of the Xapian library are made available for use from Perl. Xapian is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model as well as a rich set of boolean query operators. It's fast and scalable to hundreds of millions of documents.
The Perl ResourcePool provides a generic way to use connection caching for any kind of resources like Net::LDAP or DBI. It includes a LoadBalancer to spread load across different servers and increase overall performance and availibility of service. The ResourcePool and LoadBalancer are easily extendable to cover your needs.
JSON::XS implements JSON for Perl. Unlike other modules, its primary goal is to encode to syntactically correct JSON and flag invalid JSON while decoding. It ensures round-trip integrity of data types while being intuitive to use. Currently being the fastest of the JSON encoders available for Perl, it supports a variety of format options, such as single-line, ASCII-only, or pretty-printed, and can be tuned for speed or memory usage. It comes with a wealth of documentation describing usage and implementation details.
tgen generates a Web site from a collection of input files of a variety of types, using a set of registered HTML autogenerators. This allows, for example, the generation a Web site consisting of plain text pages, EtText formatted files, man or POD documentation, and/or custom formats, with a consistent and attractive look-and-feel. It is a driver program; the actual conversion work is done by a set of plugin filters or "autoformatters" (named *2hts[.*]).
