The rest is also donne with pbmplus, but with the standard -1x2 option for
pbmtoascii. Since you generally need to pipe a picture trough three or four
of the pbm+ programs to get a result at all, I have automated this with a
small script. These outputs could also be piped trough 'tr' to create a
desired result (e.g. change '$' to 'M'  to get more contrast)

Nuff said, here goes.
