pstext
by Dan Judd
St. Olaf College
11/29/89
This program takes plain ascii text and converts it to Postscript.
It takes a few options.
[-p ] prints portrait mode 1 page (default)
[-l ] prints landscape mode 1 page
[-ld ] dual landscape mode 2 pages per page
[-d ] dual portrait mode, prints 2 pages per page
[-n number] number of lines per page
[-t tabstring ] use a different tabstring size (NNNNNNNN default)
[-f fontname ] use a different font (Courier default)
[-s pointsize ] use a different point size (12 default)
It handles tabs and backspaces in an intelligent way in any font.
Copyright Dan Judd 1989
This program is freely redistributable, but may not be sold.
