 ```
+## Specifying GCC Function Attributes
+
+You can specify GCC function attributes for your fakes using the `FFF_GCC_FUNCTION_ATTRIBUTES` directive.
+
+### Weak Functions
+
+One usful attribute is the _weak_ attribute that marks a function such that it can be overridden by a non-weak variant at link time.  Using weak functions in combination with FFF can help simplify your testing approach.
+
+For example:
+* Define a library of fake functions, e.g. libfake.a.
+* Link a binary (you might have many) that defines a subset of real variants of the fake functions to the aforementioned fake library.
+* This has the benefit of allowing a binary to selectively use a subset of the required fake functions while testing the real variants without the need for many different make targets.
+
+You can mark all fakes with the weak attribute like so:
+```
+#define FFF_GCC_FUNCTION_ATTRIBUTES __attribute__((weak))
+#include "fff.h"
+```
+
+See the example project that demonstrates the above approach: _./examples/weak_linking_.
