Hi James:

Thanks for your interest in PLplot.

To answer your questions in order

1. To get a list of drvopt options pecify a bad driver option, e.g.,

examples/c/x01c -dev pscairo -drvopt xxxxx

2. Of course, driver options are not the whole story, and, for example,
you can specify the size of at least the xcairo result (and possibly
other cairo devices?) with the general -geometry option.

3. Our cairo device driver depends on the pango/cairo combination of
libraries, and I believe its a limitation of cairo's PostScript backend
(what we use for the pscairo device), that encapsulated PostScript is
not supported.  However, it is not too bad since you can run
single-page -dev pscairo results through ps2eps to produce 
encapsulated PostScript.

Note another set of high-quality devices are implemented by
our qt device driver.  In that case, -dev epsqt does produce
encapsulated PostScript directly.
