Change History
--------------
+2014/**/**, luaotfload v2.5
+ * Remove legacy code.
+ * Remove compatibility with the old mkluatexfontdb script.
+ * Remove test directory. Use https://bitbucket.org/phg/lua-la-tex-tests
+ instead.
+
2013/12/31, luaotfload v2.4
* Additional self-tests, now in separate file (luaotfload-diagnostics.lua)
* Better path and directory handling, especially on Windows
