+/// A macro for enforcing debug time checks to make sure all required methods are linked in
+// 
+// When using categories, it can be very easy to forget to include the
+// implementation of a category. 
+// Let's say you had a class foo that depended on method bar of class baz, and
+// method bar was implemented as a member of a category.
+// You could add the following code:
+// @implementation foo
+// GTM_METHOD_CHECK(baz, bar)
+// @end
+// and the code would check to make sure baz was implemented just before main
+// was called. This works for both dynamic libraries, and executables.
+//
+// Classes (or one of their superclasses) being checked must conform to the 
+// NSObject protocol. We will check this, and spit out a warning if a class does 
+// not conform to NSObject.
+//
+// This is not compiled into release builds.

+// If you get an error for GTMMethodCheckMethodChecker not being defined, 
+// you need to link in GTMMethodCheck.m. We keep it hidden so that we can have 
+// it living in several separate images without conflict.
+// Functions with the ((constructor)) attribute are called after all +loads
+// have been called. See "Initializing Objective-C Classes" in 
+// http://developer.apple.com/documentation/DeveloperTools/Conceptual/DynamicLibraries/Articles/DynamicLibraryDesignGuidelines.html#//apple_ref/doc/uid/TP40002013-DontLinkElementID_20
