The rmannot package, which requires a Acrobat Distiller PDF creator, is used to insert FLV (and F4V), SWF, and MP3 files into a PDF document. The files may be embedded in the document, or streamed over the Internet.
The cntdwn package is a general purpose LaTeX package (not requiring Distiller). This package defines several clocks; in particular a countdown clock. Useful if there is a time limit on the length of your presentation.
The demo file will be distributed with the upcoming version 2.1 of APB.
