michael@0	32	/* This file contains the default configuration macro definitions for */
michael@0	33	/* a standard build of the FreeType library. There are three ways to */
michael@0	34	/* use this file to build project-specific versions of the library: */
michael@0	35	/* */
michael@0	36	/* - You can modify this file by hand, but this is not recommended in */
michael@0	37	/* cases where you would like to build several versions of the */
michael@0	38	/* library from a single source directory. */
michael@0	39	/* */
michael@0	40	/* - You can put a copy of this file in your build directory, more */
michael@0	41	/* precisely in `$BUILD/config/ftoption.h', where `$BUILD' is the */
michael@0	42	/* name of a directory that is included _before_ the FreeType include */
michael@0	43	/* path during compilation. */
michael@0	44	/* */
michael@0	45	/* The default FreeType Makefiles and Jamfiles use the build */
michael@0	46	/* directory `builds/<system>' by default, but you can easily change */
michael@0	47	/* that for your own projects. */
michael@0	48	/* */
michael@0	49	/* - Copy the file <ft2build.h> to `$BUILD/ft2build.h' and modify it */
michael@0	50	/* slightly to pre-define the macro FT_CONFIG_OPTIONS_H used to */
michael@0	51	/* locate this file during the build. For example, */
michael@0	52	/* */
michael@0	53	/* #define FT_CONFIG_OPTIONS_H <myftoptions.h> */
michael@0	54	/* #include <config/ftheader.h> */
michael@0	55	/* */
michael@0	56	/* will use `$BUILD/myftoptions.h' instead of this file for macro */
michael@0	57	/* definitions. */
michael@0	58	/* */
michael@0	59	/* Note also that you can similarly pre-define the macro */
michael@0	60	/* FT_CONFIG_MODULES_H used to locate the file listing of the modules */
michael@0	61	/* that are statically linked to the library at compile time. By */
michael@0	62	/* default, this file is <config/ftmodule.h>. */
