Just to clarify Reed's comments a bit, the parsers do still depend on 
libopenvrml. However, reading a file no longer requires loading it into 
an openvrml::browser and traversing the resulting scene graph.

There is an overview of the parsing interface in the form of a brief 
user guide at <http://openvrml.org/doc/parsing>.
