Pyntor

Pyntor is a component-based presentation program, with the following design considerations: It is small (can be distributed together with presentations, even as self-extracting archive), it is extensible (download of new components via GHNS is supported), and every component only does one job, but it does it very well. Export to HTML+PNG and (fixed-size) PDF is possible. Pyntor comes prepackaged with Debian/unstable, and while it is still under development, a lot of talks in several countries have been given with it already.
