-/* 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.

- leaving the memory in a undefined state. This is the fastest
- option.
