 *
 * This macro will place a file-scope constructor and destructor into the
 * source of the module using it; this will cause the version of this file
 * to registered with the Asterisk core (and unregistered) at the appropriate
 * times.
 *
 * Example:
 *
 * \code
 * ASTERISK_FILE_VERSION(__FILE__, "\$Revision\$")
 * \endcode
 *
 * \note The dollar signs above have been protected with backslashes to keep
 * CVS from modifying them in this file; under normal circumstances they would
 * not be present and CVS would expand the Revision keyword into the file's
 * revision number.
