Is it possible to integrate an external parser into the Schliemann framework
in some way?  I suppose by the time you've written the parser, got it to
generate ASTs that Schliemann required, and linked it into Schliemann, then
you aren't so far away from doing everything yourself, although I suppose
you'd still get the navigator linkage, code folding etc.  If anyone has
managed to link in an external parser to this framework it would be useful
to know what was involved.
