+  Here we load extra AFM libraries from Context.
+  In fact, part of the AFM support is contained in font-ext.lua, for
+  which the font loader has a replacement: luatex-fonts-ext.lua.
+  However, this is only a stripped down version with everything AFM
+  removed. For example, it lacks definitions of several AFM features
+  like italic correction, protrusion, expansion and so on. In order to
+  achieve full-fledged AFM support we will either have to implement our
+  own version of these or consult with Hans whether he would consider
+  including the AFM code with the font loader.
+
+  For the time being we stick with two AFM-specific libraries:
+  font-afm.lua and font-afk.lua. When combined, these already supply us
+  with basic features like kerning and ligatures. The rest can be added
+  in due time.
