Note on installation on BeOS.

(1)
You should edit the Makefile to adjust it for BeOS.

--  The locations of the binaries pnm2ppa and calibrate_ppa may  need 
    to be changed.   (One  succesful  BeOS user put them in 
    /boot/home/config/bin )

--  The location of the manpage pnm2ppa.1  may need to be changed.

(2)  
scripts used for printing may need to be changed.  Here is
what one happy  BeOS user reported on the ppa.users@listbot.com list:
(available in the mailing lists section of http://pnm2ppa.sourceforge.net
see message #598, "No more BeOS woes",  July 21, 2000)

"Yeah, baby! :) That mother prints! Here's what I did:
 made a script called pnm

#!/bin/sh
pnm2ppa -i - -o /dev/parallel/parallel1

 and then I made my printps script as follows

#!/bin/sh
cat $1 | gs -sDEVICE=ppmraw -q -dNOPAUSE -r600 -sOutputFile=\|pnm -

 The neatto trick here is the -sOutputFile=\|pnm voodoo. For whatever reason,
 it likes that mo better. Thanks for everyone's help."
-----------------------------------------------------------------

This BeOS user apparently had difficulties with scripts using the standard
pipe  syntax  for  sending ghostscript output to pnm2ppa:
cat $1 | gs -sDEVICE=ppmraw -q -dNOPAUSE -r600 -sOutputFile=-  - | pnm 

(3)
On BeOS,  pnm2ppa does not send messages to the system log.   They go to
the standard error stream unless "silent 1" is specified in /etc/pnm2ppa.conf.

-----------------------
If you can provide us with an improved INSTALL.BEOS and Makefile,
please contact the pnm2ppa project.
