The Plucker C++ parser is
here. Plucker CVS access is documented
here.
It "works", but don't expect perfect conversions, and XHTML is not supported (shouldn't be that difficult to implement, at least for (very?) basic support, using the current HTML parsing code. I tried, but couldn't get the encoded characters to show up correctly. Note that I don't know C++, though

). There's some trial & error required to set it up, too (some parameters don't work the way they are documented). I also remember I had trouble getting the images to convert.
