Looking for a PostScript or EPS module


I’m looking for a ps (or eps module) in Ruby, like EpsGraphics2D in
java or PS::Simple in Perl …I’ve found nothing on RAA or RubyForge
but a lot of graphics libraries like RMagick, but the resulting ps
files are not very nice, nor human readable. Is there any project
started yet on this way ?
My goal is to write a little scientific geometry module in Ruby with
TeX labels and so…
Thanks a lot :
