/****s* Directory/RB_Directory
 * NAME
 *   RB_Directory -- the directory tree with the source files.
 * FUNCTION
 *   Stores information about files in a directory tree.
 *   The whole structure consist of two linked lists.  One for
 *   directory paths, and one for filenames.
 * EXAMPLE
 *   The following show an example structure.
 *     RB_Directory             RB_Path
 *     +-------+   +------+    +-------+   +-----------+
 *     |       +-->| .    |--->| ./sub |-->| ./sub/sub |

 * ATTRIBUTES
 *   * first    --  first RB_Filename in the list of files
 *   * current  --  the last file that was returned in
 *                  RB_Get_Next_Filename.
 *   * last     --  the last RB_Filename in the list of files
 *                   used for the insert operation
 *   * first_path -- first RB_Path in the list of paths.
