+/* INTRODUCTION
+
+   The ork1sim has various parameters, that are set in configuration files
+   like this one. The user can switch between configurations at startup by
+   specifying the required configuration file with the -f <filename.cfg> option.
+   If no configuration file is specified or1ksim searches for the default
+   configuration file sim.cfg. First it searches for './sim.cfg'. If this
+   file is not found, it searches for '~/or1k/sim.cfg'. If this file is
+   not found too, it reverts to the built-in default configuration.
+
+   NOTE: Users should not rely on the built-in configuration, since the
+         default configuration may differ between version.
+         Rather create a configuration file that sets all critical values.
+
+   This file may contain (standard C) comments only - no // support.
+
+   Configure files may be be included, using:
+   include "file_name_to_include"
+
+   Like normal configuration files, the included file is divided into
+   sections. Each section is described in detail also.
+
+   Some section have subsections. One example of such a subsection is:
+
+   device <index>
+     instance specific parameters...
+   enddevice
+
+   which creates a device instance.
