Zero Install is a decentralized cross-distribution software installation system. It allows software developers to publish programs directly from their own Web sites, while supporting features familiar from centralized distribution repositories such as shared libraries, automatic updates, and digital signatures. It is intended to complement, rather than replace, the operating system's package management. 0install packages never interfere with those provided by the distribution.
Kom stands for "Keep old mails". It imports email messages into a MySQL database, and provides a frontend in GTK 2 to search and browse the archived messages. Some options can be used to incrementally import email (per month, for example). It can also export messages stored in the database, in mbox format or one-message-per-file format, and generate some statistics.
