sam2p is a Unix commandline utility that converts many raster (bitmap) image formats into Adobe PostScript or PDF files. The images are not vectorized. It gives full control to the user to specify standards-compliance, compression, and bit depths. It is common that sam2p can compress an image down to an 50kB Level1 PostScript file without quality loss, while other popular converters produce multi-megabyte output. It provides some Level3 compression filters even on Level1 devices.
MKHINDEX generates HTML directory listings like the "Option Indexes" functionality of Apache. Other than the Web server, these listings are static. They greatly increase the performance of the Web server if you use it as a file server. MKHINDEX has been tested on Windows XP, Gentoo Linux, and Mac OS X.
AKFAvatar is a fancy graphical user interface for text oriented applications where an avatar appears on the screen and provides information in a balloon. It also supports recorded audio files.

A number of ready-to-use applications and modules are provided, including a text viewer and a module that makes question-answer exercises. For POSIX-compatible operating systems there is a man page viewer and a terminal emulator, which makes it possible to run many existing terminal-based programs in this fancy environment.
