From 5868b9d15ebca57f7ead09140e139dbec798e1ce Mon Sep 17 00:00:00 2001
From: Khaled Hosny <khaledhosny@eglug.org>
Date: Fri, 12 Nov 2010 07:05:22 +0200
Subject: Remove --database-dir and --sys options

* --database-dir is useless anyway since we don't support loading names
  database from arbitrary path.
* --sys (and mkluatexfontdb-sys) are dangerous since we will load user
  specific fonts (in ~/.fonts for example) which can not be loaded by
  other users (can be security concern as well). If there is real need,
  we should then implement it properly.

+ some clean up and less code duplication in mkluatexfontdb.
