R-beta: Encapsulated Postscript output with R-0.49

[Steve Shiboski]

I've noticed that the postscript files produced by R-0.49
come up inverted in my postscript previewer. Also, they
do not behave like encapsulated postscript files so they
can't be imported into LaTeX documents. If I remove lines
with page-oriented commands like "%%Page", "%%Orientation",
"\bp" and "\ep", the resulting files seem to behave like 
legitimate eps files. I've been using the Perl script below
to automate the process:

################################################################
# Perl script to produce encapsulated Postscript-like output
# from R-0.49-produced Postscript files. (Invoke using the name
# of a Postscript file as the argument.)
################################################################
#!/usr/local/bin/perl
open(FILE,"./$ARGV[0]");
while (<FILE>) { 
if (!/\%\%Page./ && !/\%\%Orientation./ && !/\/bp/ && !/\/ep/ && !/^bp\b/ && !/^ep\b/) 	{
	s/^\%\!PS-Adobe-3.0/\%\!PS-Adobe-3.0 EPSF-3.0/;
	print "$_"; 
		}
}
################################################################

Unless I am the only person experiencing problems with postscript
output, I think it would be a worthwhile project to modify the
existing postscript driver to output compliant eps files as an option.
If I had the requisite knowledge of postscript, I would volunteer...
