+/* 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.
