// ModuleInfo_parse => class defining a parsing object
//	ModuleInfo_parse needs a class ModuleInfo_scan, which defines the scanner.
// %prefix or option -p xx determines name of this class; if not used,
// defaults to 'ModuleInfo_scan'
//
// constructor fills in the tables for this grammar; give it a size
//    to determine size of state and value stacks. Default is 150 entries.
// destructor discards those state and value stacks
//
// int ModuleInfo_parse::ModuleInfoparse(ModuleInfo_scan *) invokes parse; if this returns,
//	it can be recalled to continue parsing at last point.
// void ModuleInfo_parse::ModuleInforeset() can be called to reset the parse;
//	call ModuleInforeset() before ModuleInfo_parse::ModuleInfoparse(ModuleInfo_scan *)
