 /** \file

+ *  \brief Special function/variable attribute macros.
  *
- *  This file contains macros for applying GCC specific attributes to functions and variables to control various
- *  optimiser and code generation features of the compiler. Attributes may be placed in the function prototype
- *  or variable declaration in any order, and multiple attributes can be specified for a single item via a space
- *  separated list.
- *
- *  On incompatible versions of GCC or on other compilers, these macros evaluate to nothing unless they are
- *  critical to the code's function and thus must throw a compiler error when used.
+ *  \copydetails Group_FuncVarAttributes
  *
  *  \note Do not include this file directly, rather include the Common.h header file instead to gain this file's
  *        functionality.
