Compface - 48x48x1 image compression and decompression
Copyright (c) James Ashton 1990.
Written 89/11/11

Feel free to distribute this source at will so long as the above
message and this message are included in full.

The programme (two programmes really - but they're just links to each
other) converts 48x48x1 images to and from a compressed format.  The
uncompressed images are expected to contain 48x48/4 (576) hex digits.
All other characters and any `0's followed by `X' or `x' are ignored.
Usually the files are 48 lines of "0x%04X,0x%04X,0x%04X,".  The
compressed images contain some number of printable characters.  Non
printable characters, including ` ' are ignored.  The purpose of the
programme is to allow the inclusion of face images within mail headers
using the field name `X-face: '.

The programmes make use of a library which can be used to allow the
compression and decompression algorithms to be used in other
programmes such as mail despatchers and mail notification daemons.

A small amount of editing in the Makefile may be required to get it
going - mainly setting EXECUTABLE to what you want and putting the
manual entry in the right place.

Another peoblem with the copyright of this source code is that the
copyright message in the source files and in the readme file is conflicting.
The following mail from the author should clear that up:
