DESCRIPTION
Mugs interactively converts grey-scale images in the form of
picfile(9.6) into 48x48 icons. It is designed to run in a
pipe, reading the picture from standard input unless a sin-
gle file is given on the call. Mugs displays a large
approximation to the original picture and a matrix of 48x48
icons of varying contrast and brightness. Button 1 selects
one of the icons. Button 2 offers the menu entries:
in Zoom in to a finer contrast/brightness range around the
selected icon. Repeated ins will zoom in farther.

cropped icons will be displayed.

write
Write the selected icon to standard output. Each write
