 Before it's non-embarrassingly releasable:
 
- - more flexible running modes
-    + at least some ability to chain actions within the same run:
-      "agedu -s dirname -w" would seem handy.
+ - now we have a configure framework, actually use it to:
+    * configure use of stat64
+    * configure use of Linux syscall magic replacing readdir
+       + later glibcs have fdopendir, hooray! So we can use that
+	 too, if it's available and O_NOATIME is too.
 
- - work out what to do about atimes on directories in the absence of
-   the Linux syscall magic
-    * one option is to read them during the scan and reinstate them
-      after each recursion pop. Race-condition prone.
-    * marking them in a distinctive colour in the reports is another
-      option.
-    * a third option is simply to ignore space taken up by
-      directories in the first place; inaccurate but terribly simple.
-    * incidentally, sometimes open(...,O_NOATIME) will fail, and
-      then we have to fall back to ordinary open. Be prepared to do
-      this, which probably means getting rid of the icky macro
-      hackery in du.c and turning it into a more sensible run-time
-      abstraction layer.
-
- - polish the plain-text output to make it look more like du
-    + configurable recursive output depth
-    + show the right bits last
-
- - cross-Unix portability:
-    + use autoconf
-       * configure use of stat64
-       * configure use of /proc/net/tcp
-       * configure use of /dev/random
-       * configure use of Linux syscall magic replacing readdir
-          + later glibcs have fdopendir, hooray! So we can use that
-	    too, if it's available and O_NOATIME is too.
-       * what do we do elsewhere about _GNU_SOURCE?
-
- - man page, licence.
+ - man page, --version.

       straight to terminfo: generate lines of attribute-interleaved

-    + I think the attribute-interleaved text might be possible to do
-      cunningly, as well: we autodetect a basically VT-style
-      terminal, and add 256-colour sequences on the end. So, for
-      instance, we might set ANSI-yellow foreground, set ANSI-red
-      background, _then_ set both foreground and background to the
-      appropriate xterm 256-colour, and then display some
-      appropriate character which would have given the right blend
-      of the ANSI-16 fore and background colours. Then the same
-      display code should gracefully degrade in the face of a
-      terminal which doesn't support xterm-256.
-       * current best plan is to simulate the xterm-256 shading from
