37 * @short_description: Object representing a shaping plan
38 * @include: hb.h
39 *
40 * Shape plans are an internal mechanism. Each plan contains state
41 * describing how HarfBuzz will shape a particular text segment, based on
42 * the combination of segment properties and the capabilities in the
43 * font face in use.
44 *
45 * Shape plans are not used for shaping directly, but can be queried to
46 * access certain information about how shaping will perform, given a set
47 * of specific input parameters (script, language, direction, features,
48 * etc.).
49 *
50 * Most client programs will not need to deal with shape plans directly.
