#*  This sub-Makefile is in charge of detecting the current platform        *
#*  It sets some variables accordingly. Namely :                            *

#*   PLATFORM     The detected platform. This will default to "ansi" if     *
#*                auto-detection fails.                                     *

#*   BUILD        The configuration and system-specific directory. Usually  *
#*                'freetype/config/$(PLATFORM)' but can be different when   *
#*                a specific compiler has been requested on the             *
#*                command line..                                            *

#*   CONFIG_RULES The Makefile to use. This usually depends on the compiler *
#*                defined in the 'CC' environment variable.                 *
#*                                                                          *
#*   DELETE       The shell command used to remove a given file             *
#*   COPY         The shell command used to copy one file                   *
#*                                                                          *
#*  You need to set the following variable(s) before calling it:            *
#*                                                                          *
#*    TOP         The top-most directory in the FreeType library source     *
#*                hierarchy. If not defined, it will default to '.'         *
#*                                                                          *
