/* INTRODUCTION
24
 
25
   The ork1sim has various parameters, that are set in configuration files
26
   like this one. The user can switch between configurations at startup by
27
   specifying the required configuration file with the -f  option.
28
   If no configuration file is specified or1ksim searches for the default
29
   configuration file sim.cfg. First it searches for './sim.cfg'. If this
30
   file is not found, it searches for '~/or1k/sim.cfg'. If this file is
31
   not found too, it reverts to the built-in default configuration.
32
 
33
   NOTE: Users should not rely on the built-in configuration, since the
34
         default configuration may differ between version.
35
         Rather create a configuration file that sets all critical values.
36
 
37
   This file may contain (standard C) comments only - no // support.
38
 
39
   Configure files may be be included, using:
40
   include "file_name_to_include"
41
 
42
   Like normal configuration files, the included file is divided into
43
   sections. Each section is described in detail also.
44
 
45
   Some section have subsections. One example of such a subsection is:
46
 
47
   device 
48
     instance specific parameters...
49
   enddevice
50
 
51
   which creates a device instance.
