 * This file defines macros for common options that can be used to

 * template containing English descriptions for options wrapped in
 * gettext(). xgettext can be used to extract translatable
 * strings. These strings can then be translated by anyone familiar
 * with GNU gettext. gen_xmlpool.py takes this template and fills in
 * all the translations. The result (options.h) is included by
 * xmlpool.h which in turn can be included by drivers.
 *
 * The macros used to describe otions in this file are defined in
 * ../xmlpool.h.
