[gutvol-d] PG extensions to RST not recognized

I've made some progress with the RST but I'm still having issues. Some of the PG extensions don't seem to be recognized. For instance: System Message: ERROR/3 (<string>, line 21) Unknown directive type "byline". .. byline:: BY PURNENDU NARAYANA SINHA, M. A., B. L. The image directive was working fine before but putting "byline" in messes it up: System Message: ERROR/3 (<string>, line 25) Error in "image" directive: no content permitted. .. image:: images/bhagaf004.jpg It doesn't seem to like vspace either: System Message: ERROR/3 (<string>, line 34) Error in "vspace" directive: no content permitted. .. vspace:: pb You can see all the problems here: http://epubmaker.pglaf.org/cache/20120325054028/ James Simmons
