+micro-typographic extensions that were introduced by pdfTeX and have
+since propagated to XeTeX and LuaTeX: most prominently character
+protrusion and font expansion, the adjustment of kerning and interword
+spacing, hyphenatable letterspacing and the possibility to disable all
+or selected ligatures.  These features may be applied to customisable
+sets of fonts.  All micro-typographic aspects of the fonts can be
+configured in a straight-forward and flexible way.  Settings for
+various fonts are provided.  An alternative package @code{letterspace},
+which also works with plain TeX, is included in the bundle.")
