+    Adobe Glyph List.
+    -------------------------------------------------------------------
+
+    Context provides a somewhat different font-age.lua from an unclear
+    origin. Unfortunately, the file name it reads from is hard-coded
+    in font-enc.lua, so we have to replace the entire table.
+
+    This shouldn’t cause any complications. Due to its implementation
+    the glyph list will be loaded upon loading a OTF or TTF for the
+    first time during a TeX run. (If one sticks to TFM/OFM then it is
+    never read at all.) For this reason we can install a metatable that
+    looks up the file of our choosing and only falls back to the
+    Context one in case it cannot be found.
