 * the gimprc file considered extraneous to the operation of the GIMP.
 * Plug-ins that need configuration information can expect it will be
 * stored in the user gimprc file and can use this procedure to
 * retrieve it. This query procedure will return the value associated
 * with the specified token. This corresponds _only_ to entries with

 * not corresponding to this format will cause warnings to be issued on
 * gimprc parsing and will not be queryable.
