  *
  *  cmAddCustomCommandCommand defines a new command that can
  *  be executed within the CMake
+ *
+ *  In makefile terms this creates new target in the following form:
+ *  OUTPUT1: SOURCE DEPENDS
+ *           COMMAND ARGS
+ *  OUTPUT2: SOURCE DEPENDS
+ *           COMMAND ARGS
+ *  ...
+ *  Example of usage:
+ *  ADD_CUSTOM_COMMAND(
+ *             SOURCE ${VTK_TIFF_FAX_EXE} 
+ *             COMMAND ${VTK_TIFF_FAX_EXE}
