% This utility provides functionality approximately equivalent to the Unix

% `enscript' program. It prints plain text files using a single font.

% It currently handles tabs and formfeeds, but not backspaces.
|
|
|
22 |
% It will line-wrap when using fixed-pitch fonts.
|
|
|
23 |
% It will also do kerning and width adjustment.
