72 * @abstract:
73 * Macro definitions used to `#include` specific header files.
74 *
75 * @description:
76 * The following macros are defined to the name of specific FreeType~2
77 * header files. They can be used directly in `#include` statements as
78 * in:
79 *
80 * ```
81 * #include FT_FREETYPE_H
82 * #include FT_MULTIPLE_MASTERS_H
83 * #include FT_GLYPH_H
84 * ```
85 *
86 * There are several reasons why we are now using macros to name public
87 * header files. The first one is that such macros are not limited to
88 * the infamous 8.3~naming rule required by DOS (and
89 * `FT_MULTIPLE_MASTERS_H` is a lot more meaningful than `ftmm.h`).
90 *
91 * The second reason is that it allows for more flexibility in the way
92 * FreeType~2 is installed on a given system.
