    The parser that I'm working on does compile the code, it's is used as an aid in
a development environment (currently only SetEdit, but will support Emacs soon, and
RHIDE when new versions come [I haven't checked v4.1.7, maybe it has the sLisp that
I need]).  It displays information about your code and can do variable-name
completion as well as listing the contents of a struct/union/simple class.  It is
only designed to work with compilable code and thus is allowed to accept a superset
of C/C++.
