% gslp.ps - format and print text
|
|
|
|
% 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.
|
|
% Currently it neither truncates nor wraps over-length lines.
|
|
% It only works with fixed-pitch fonts.
|
|
% Flags implemented: -12BclrR -b -f -F -L -p
|
|
% Flags added:
|
|
% -T<n> for defining the tab width
|
|
% -P<n> for setting the first page to print
|
|
% -Q<n> for setting the last page to print
