GIFView 2.2 is a gif file viewer for use with vt320 terminals. It 
currently runs on UNIX BSD4.3 and System V, but should be easily
portable to any platform as it uses only printf and several other
stdio commands, no termcap/terminfo.

It runs interactively, with the input gif file specified on the
command line. It has three degrees of shading for each point:
black, grey and white. The threshold values control how
bright a point must be to be displayed in grey or white,
for half and fullbrite respectively. A simple colour balance
machanism, to convert from RGB to 8-bit grayscale, is also
included.

However, GIFView's best feature is its image packer/optimiser,
which cuts the number of characters used to its minimum without
losing picture quality. This allows images to be larger than
the usual 16x6 96-character display, depending on their complexity.
