%  File: imag:/users/local/a2ps/header.ps
%  Created: Tue Nov 29 12:14:02 1988 by miguel@imag (Miguel Santana)
%  Version: 2.0
%  Description: PostScript prolog for a2ps ascii to PostScript program.
%=20
%  Edit History:
%  - Original version by evan@csli (Evan Kirshenbaum).
%  - Modified by miguel@imag to:
%    1) Correct an overflow bug when printing page number 10 (operator
%	cvs).
%    2) Define two other variables (sheetwidth, sheetheight) describing
%	the physical page (by default A4 format).
%    3) Minor changes (reorganization, comments, etc).
%  - Modified by tullemans@apolloway.prl.philips.nl
%    1) Correct stack overflows with regard to operators cvs and copy.
%       The resulting substrings where in some cases not popped off=20
%       the stack, what can result in a stack overflow.
%    2) Replaced copypage and erasepage by showpage. Page througput
%       degrades severely (see red book page 140) on our ps-printer
%       after printing sheet 16 (i.e. page 8) of a file which was=20
%       actually bigger. For this purpose the definitions of startdoc
%       and startpage are changed.
%  - Modified by Tim Clark <T.Clark@uk.ac.warwick> to:
%    1) Print one page per sheet (portrait) as an option.
%    2) Reduce size of file name heading, if it's too big.
%    3) Save and restore PostScript state at begining/end. It now uses
%	conventional %%Page %%Trailer markers.
%    4) Print one wide page per sheet in landscape mode as an option.
%  - Modified by miguel@imag.fr to
%    1) Add new option to print n copies of a file.
%    2) Add new option to suppress heading printing.
%    3) Add new option to suppress page surrounding border printing.
%    4) Add new option to change font size. Number of lines and columns
%	are now automatically adjusted, depending on font size and
%	printing mode used.
%    5) Minor changes (best layout, usage message, etc).
%  - Modified by kanazawa@sra.co.jp to:
%    1) Handle Japanese code
%  - Modified by utashiro@sra.co.jp to:
%    1) Fix bug in printing long label
%    2) Handle carriage-return
%    3) Specify kanji-ascii character retio
%    4) Add footer label
%    5) Change filename->fname becuase ghostscript has operator filename
%    6) Support three different font style
%    7) Incorporate B4 paper support and punchmark contributed
%       by Masami Ueno <cabbage@kki.esi.yamanashi.ac.jp>
