ChangeLog

v0.6 2004/01/15
	(2004/01/15) PS1 - treat unknown file types as text if they
	contain no unprintable characters
	(2003/12/11) PS1 - added "-l" option to lpr-orig, which triggers
	"raw" mode in CUPS, preventing CUPS filters from messing with our
	pre-formatted data. For BSD lpr, the "-l" option does no harm.
	
v0.4 2004/12/06
	(2004/12/06) PS1 - first public release
	(2003/06/04) PS1 - only call ppdfilt if necessary
	(2002/04/27) PS1 - removed references to /dev/stdout
	(2002/04/27) PS1 - fall back to default dimensions if psdim fails
