LATEST INFO
===========
a2ps has been around a long time and produces very nice 2 page listings
on single sheets of a4 in a postscript laser printer. Many thanks to the
original authors for this fine product.
This version has been rebuilt for OS2 (ver1.1 or higher) and the command file
list.cmd has been added to simplify the user interface. Current default for
output is LPT1: but this can be changed (as can the temp file name) by
altering LIST.CMD.
USAGE
=====
1) Place the following line in config.sys
"set header_ps=c:\<list>\header.ps"
where <list> is full path of file header.ps
2) Put both list.cmd and a2ps.exe on a path which will be searched.
3) Type command
"list <filename>"
for output.

OLD INFO
========
a2ps \- formats an ascii file for printing in a postscript printer;
very nice and compact format for program listings.
SYNOPSIS
a2ps [-b] [-f] [-i] [-n] [-n{bfinrv}] [-r] [-v] [file1] [file2] [...]
DESCRIPTION
a2ps formats files "file1", "file2", ... for printing in a postscript
printer; if no file is given, a2ps reads from the standard input.
Format used is very nice and compact: two pages on each physical page,
borders surrounding pages, headers with useful information (page number,
printing date, file name), line numbering, etc. Very useful to
archive listings of programs.
Options offered by a2ps are the following:
-b
Force printing binary files. By default, binary files printing is
stopped before second page (see -nb option).
-f
Fold lines too large to be printed inside the borders (default option).
Max size is actually 86 characters.
-i
Interpret TAB, BS and FF characters (default option). TAB is replaced by
enough spaces to reach next tab stop while BS and FF have their meanings.
-n
Output lines are preceded by line numbers, numbered sequentially from 1
(default option).
-nb
Don't print binary files. To detect such a file we make use of a
very simple heuristic: if the first page of the file contains at
less 75% of non-printing characters, it's a binary file. First page
is always printed.
-nf
Cut lines too large (don't fold).
-ni
Don't interpret TAB, BS and FF characters. They will be printed
according to -v option.
-nn
Don't number output lines.
-nr
Sheet numbering (see -r option) must be continue for all files (don't
reset on new file).
-nv
Replace non-printing characters by a space.
-r
Reset sheet numbering for each new file (default option). Sheet numbering
is used to number physical pages (sheets printed) and is placed
in the bottom of each physical page. It differs from page numbering: logical
pages of file been printed.
-v
Replace non-printing characters so that they are listable and easy to identify
(default option). Control characters (ascii codes lower than 0x20) are
printed like ^X for ctrl-x; the delete character (hex 0x3f) is printed
as ^?. Non ascii characters (with the high bit set) are printed as M-
(for meta) followed by the character of the low 7 bits. TAB, BS and FF are
handled like non-printing characters if -ni option was taked.
USAGE
a2ps sends formatted file to standard output. User could redirect this output
to a file or pipe it directly to a print command, like lpr in UNIX:
a2ps file1 > file2
a2ps file1 | lpr -l
Don't forget -l option in last line, if you want that lpr interprets your
postscript program.
This filter must be used only with text files. Avoid specially output from
TeX, troff or any other text formatter.
NB a2ps requires access to header file, which contains the Postscript
pre-amble. The file name should be put in the environment variable
HEADER_PS. If this variable is not defined a2ps will look in the
current directory. (This was added for the dos version).
