freshmeat.net maintains the Web's largest index of Unix and cross-platform software, themes and related "eye-candy", and Palm OS software. Thousands of applications, which are preferably released under an open source license, are meticulously cataloged in the freshmeat database, and links to new applications are added daily. Each entry provides a description of the software, links to download it and to obtain more information, and a history of the project's releases, so readers can keep up-to-date on the latest developments.
