Anti-Spam Agent for Novell NetMail is a replacement for SpamAssassin's spamd. It will tell the NetMail server to send all new email to it for spam checking. If SpamAssassin determines that the email is spam, you can either have it deleted, or have "X-Spam-Flag: YES" added to the message header. This project also includes assistance for others to write their own NetMail agents.
CleanPOP cleans your POP3 mailbox based on your local mbox, so local anti-spam tools can be applied to Web-mail and other non-local clients. After you've downloaded and processed mail from the POP server, CleanPOP logs in and purges email messages which match locally-added spam headers or are older than a configured expiration time. It aims to be safe by not deleting unfetched emails (unlike other email filters), and efficient by checking only new messages. It's also useful for fetchmail users, who have no option to "delete after X days".
DiaNa is a Perl framework designed to process a huge amount of data, performing from very easy to very complex tasks in a very efficient, spreadsheet-like, batch fashion. DiaNa also features an interactive Perl/Tk GUI, layered on the top of several batch shell-scripts. The DiaNa syntax is a very small and orthogonal superset of the underlying Perl syntax, which allows, for example, comfortable addressing of file tokens and profitable use of file formats throughout the data processing.
IDX-DocBook2LaTeX is a stylesheet which translates DocBook documents into LaTeX. It is written in Perl, using the XML::XPathScript package from AxKit. It features the ability to handle tables, indices, figures, footnotes, and more. The XSLT-like templating philosophy built into XPathScript makes it easy to extend.
