+fc-loadtool batch mode
+======================
+
+In addition to the interactive mode described above, fc-loadtool can be used in
+a scripted or batch mode where it makes contact with the target device as it
+boots, interrupts and diverts the boot process to loadagent, executes a given
+command script, cleans up the target state as appropriate (usually powers off)
+and exits.  This mode is used by the FreeCalypso factory for initial flash
+programming on the device production line, but it can also be used by end users
+to install firmware updates in a more automated manner.
+
+The batch mode is entered when there is a command script given on the
+fc-loadtool invokation command line.
