+  "Update your toolchain file as follows.
 
-# These are macros intended to be used only when crosscompiling in the 
-# toolchain-file and only if the compiler is not able to link an 
-# executable by default (usually because they need user-specific 
-# linker files which describe the layout of the target memory).
-#
-# It offers the following macros:
-#
-# macro CMAKE_FORCE_SYSTEM(name version processor)
-#   Set CMAKE_SYSTEM_NAME, CMAKE_SYSTEM_VERSION and CMAKE_SYSTEM_PROCESSOR
-#
-# macro CMAKE_FORCE_C_COMPILER(compiler compiler_id sizeof_void_p)
-#   Set CMAKE_C_COMPILER to the given compiler and set CMAKE_C_COMPILER_ID
-#   to the given compiler_id. This Id is used by cmake to construct the filename
-#   of the system-compiler.cmake file. For C also the size of a void-pointer
-#   has to be predefined.
-#
-# macro CMAKE_FORCE_CXX_COMPILER(compiler compiler_id)
-#   The same as CMAKE_FORCE_C_COMPILER, but for CXX. Here the size of 
-#   the void pointer is not requried.
-#
-# So a simple toolchain file could look like this:
-#
-# INCLUDE (CMakeForceCompiler)
-# CMAKE_FORCE_SYSTEM ("Generic"   "0.0"   "hc12")
-# CMAKE_FORCE_C_COMPILER   (chc12 FreescaleCHC12  2)
-# CMAKE_FORCE_CXX_COMPILER (chc12 FreescaleCHC12)
