-/** wxDllLoader is a class providing an interface similar to unix's
- dlopen(). It is used by the wxLibrary framework and manages the
- actual loading of DLLs and the resolving of symbols in them.
- There are no instances of this class, it simply serves as a
- namespace for its static member functions.

+// this macro makes this slightly less painful by allowing you to specify the
+// type only once, as the first parameter, and creating a variable of this type
+// called "pfn<name>" initialized with the "name" from the "dynlib"
