libgraphite2-doc binary package in Ubuntu Xenial amd64

 Graphite is a system that can be used to create and use "smart fonts" capable
 of displaying writing systems with various complex behaviors, such as:
 contextual shaping, ligatures, reordering, split glyphs, bidirectionality,
 stacking diacritics and complex positioning.
 .
 This library was designed and developed by the NRSI (Non-Roman Script
 Initiative) within SIL International (www.sil.org) to act as a complement to
 other smart font rendering technologies with limited practical local
 extensibility. Its purpose is to help meet the needs of a very large number
 of "minority language" communities for local extensibility of complex script
 behaviors.
 .
 The behavior of the rendering engine for a given writing system is specified
 through extra tables added to a TrueType font. These tables are generated by
 compiling a GDL (Graphite Description Language) source file into a font using
 grcompiler.
