[kepler-users] saving workflow in eps format

[Edward A. Lee]

I've been using the itextPDF mechanism Christopher describes below,
and it's far more convenient than the other alternatives if you
are going to use the PDF in Latex.  The reason it is more convenient
is that it exports the PDF on a correctly sized page.  With the printing
mechanisms you get it on an 8.5x11 (or A4) page, or you have to manually
set the page size, which is a royal pain...

Too bad that code is AGPL'd. If it weren't, we could just include
it with Ptolemy II.  But AGPL is not truly "free software."
It is encumbered quasi-free software...
