** This compiler reads a C++ header file with class definitions and ouputs
** C++ code to build a meta class. The meta data includes public methods
** (not constructors, destructors or operator functions), signals and slot
** definitions. The output file should be compiled and linked into the
** target application.
**
** C++ header files are assumed to have correct syntax, and we are therefore
** doing less strict checking than C++ compilers.
**
** The C++ grammar has been adopted from the "The Annotated C++ Reference
** Manual" (ARM), by Ellis and Stroustrup (Addison Wesley, 1992).
**
** Notice that this code is not possible to compile with GNU bison, instead
** use standard AT&T yacc or Berkeley yacc.
