LISTR is a text formatter.  It was written with the primary
objective of formatting program listings and other simple ASCII text
files for printing.  With LISTR you may add headers and footers that
include file names and dates, page numbers and other text.  You can
number lines, control margins, and keep important blocks of text
together on a page.  Text may be included in the margins (e.g., line
numbers, change bars, a box around a page).

This is a sample text file which will be formatted and
displayed by LISTR.  LISTR indents the text, and adds the
titles to the top and bottom.  This paragraph is indented
by the TextLen and LeftMgn commands included in the file
LISTR.DEM.  The file LISTRCMD.DEM sets the page format.
