/* This header file defines the API that loadable commands can use. In many
   of these commands C++ instances of cmMakefile of cmSourceFile are passed
   in as arguments or returned. In these cases they are passed as a void *
   argument. In the function prototypes mf is used to represent a makefile
   and sf is used to represent a source file. The functions are grouped
   loosely into four groups 1) Utility 2) cmMakefile 3) cmSourceFile 4)
   cmSystemTools. Within each grouping functions are listed alphabetically */
