/* */
|

/* - You can modify this file by hand, but this is not recommended in */

/* cases where you would like to build several versions of the */

/* library from a single source directory. */
|
|
/* */
|
|
/* - You can put a copy of this file in your build directory, more */

|
/* is the name of a directory that is included _before_ the FreeType */
|
|
/* include path during compilation. */
|

/* */
|

/* The default FreeType Makefiles and Jamfiles use the build */
|
|
/* directory `builds/<system>' by default, but you can easily change */
|
|
/* that for your own projects. */
|
|
/* */
|
|
/* - Copy the file <ft2build.h> to `$BUILD/ft2build.h' and modify it */
|
|
/* slightly to pre-define the macro FT_CONFIG_OPTIONS_H used to */
|

/* locate this file during the build. For example, */
