    13 // Description:

    14 // All patchable constants need to be defined in a separate file.

    15 // Care should be taken not to define the constant data in the same source file in which

    16 // they are referred, lest the compiler inline's it. If inlined, the data has no storage

    17 // location and cannot be patched.

    18 // Hence, the definition of data must be put in a separate source file and they must be 

    19 // referred in other source files by using the 'extern' qualifier.

    20 //
