/*
* This file is #include'd by aspiring per-class stub routines.
* Each STUBMETHODS() macro creates a Present tag indicating that the
* corresponding library is not loaded, and a Methods() routine
* which complains if called.
* They're useful as components of a libstub.a library used to link with
* applications that only need a few of the OOGL object-types.
* Assuming classA, classB, etc. are needed, link as in
* -lgeom -lclassA -lclassB ... -lgeom -lstub -lbbox -l3d -lm
*
* Use of the method-specific stubs (e.g. libstubdraw) is quite different;
* see stubdraw.c.
