Thanks for the tidbits, what a great idea regarding these directives.
I also understand how to get the headers to work.  

But is there a way to specify the command line options in the directives as
well?  I'd like to turn off the stylesheets (or specify my own).  But since
I'm using core.publish_string(), I don't know how to set the command line
switches?

I'm currently pre-processing a file into a reStructuredText format, then
call core.publish_string().  There probably is a better way, by writing my
own reader, but not sure how Reader class is used.

Thanks,
Albert
