// Comments from SDK dlls/util.h:
//! This is the glue that hooks .MAP entity class names to our CPP classes.
//! The _declspec forces them to be exported by name so we can do a lookup with GetProcAddress().
//! The function is used to intialize / allocate the object for the entity.

// Adapted from LINK_ENTITY_TO_FUNC in adminmod linkfunc.cpp.
