Blosxom
Blosxom (pronounced "blossom") is a lightweight yet feature-packed weblog application designed from the ground up with simplicity, usability, and interoperability in mind. You can edit your blog posts off a flat file database with your favorite editor. All entries can be done with regular text files. Create, edit, rename, and delete entries on the command-line, via FTP, WebDAV, or anything else you might use to manipulate your files. There's no import or export; entries are nothing more complex than title on the first line, body being everything thereafter. Blosxom's plug-in architecture allows the core of Blosxom to remain small and sleek while providing room for extension and integration into different environments and uses. Blosxom is simple, straightforward, minimalist Perl affording even the dabbler an opportunity for experimentation and customization. Blosxom is Open Source and free for the taking and altering.
