 compare.pl   Use this perl script to compare two block devices of two machines.
-read_pc.pl   This scripts shows the values of the generation counters.
+read_gc.pl   This scripts shows the values of the generation counters.
 show_size    Displays the size of a block device.

+uml-screen-debug
+   starts an uml inside a screen session, and attaches gdb.
+   All VCs, the console and the gdb are screen windows,
+   so you can attach to them wherever you like, and you don't have your
+   desktop cluttered with 9 xterms...
+
+   Intended usage:
+   xterm -fg white  -bg black    -geom 132x80 -e ./uml-screen-debug uml-1
+   xterm -fg yellow -bg darkblue -geom 132x80 -e ./uml-screen-debug uml-2
+
+uml_profile-USER@HOSTNAME
+   configuration file for uml-screen-debug, so it knows what ubdX and
+   network ips to configure.
+
+= gdb helpers for uml =
+uml-2.4.gdbinit
+uml-2.6.gdbinit
+   look into them to see what they are good for.
