comes from the current date. The version from from sql/database-migrate.txt.
Also commit changes to front page. I still need to hook it into the
install process.

Add note on how to disable cdp in IOS.

program-agents.

(in particular for partition 4).  I learned the hard way that they can
interfere with correct booting of a new image.

Event system documentation and tweaks:

	* event/sched/event-sched.c: The snapshot event got left out of
	the list of events that send back a complete event.  If a top
	level sequence stops with an error, automatically send a report.

	* event/sched/group-agent.c, event/sched/timeline-agent.c: When
	handling a complete event, return true if the event was consumed.

	* event/sched/node-agent.cc: Clean the "/local/logs" loghole on
	the node before taking a snapshot of the disk image.

	* event/sched/simulator-agent.cc, event/sched/simulator-agent.h:
	Made send_report non-static so it can be called when a sequence
	errors out.  Actually check the clear flag when dumping report
	data.

	* lib/libtb/tbdefs.c: Add a comment about updating the event
	scheduler when a new object type is added.

	* tbsetup/ns2ir/sim.tcl.in: Check the OSIDs passed to the "reload"
	and "snapshot-to" events.

	* utils/loghole.1: Mention early and often the directories that
	gets sync'd.  Document the 'change' action and new options for
	'clean'.

	* utils/loghole.in: Use rsync's '--include-from' option so we
	don't have to run rsync separately for each directory.  Add a
	'change' action that lets people mess with the metadata of an
	existing archive.  Make the 'clean' action also remove log files
	on the nodes.  Only rsync node's whose OS's support ssh.  Grab
	logs from delay nodes.

	* www/tutorial/advanced.html: Update the program agent examples to
	use the new form.

	* www/tutorial/eventsystem.html: First cut at an event system
	reference manual that includes sequences, timelines, and other
	new features.

	* www/tutorial/loghole.html: Just a pointer to the man page on ops
	for now.

	* www/tutorial/nscommands.html: Add a section about capturing
	parameters from the 'opt' array.

	* xmlrpc/emulabserver.py.in: Add an osid.info() method that
	returns information about a single OSID.

from the DB.

 * brainstem-reset.cc: comments.

is reset, then the GP (it seems that the GP acts as the I2C router... so
moto has to be reset first -- this may not be true, not sure yet).  Reset
can be toggled in pilot by sending a USR2 to the pilot process.  If reset
is sent while robot is executing any sort of move, the only way to recover
is to kill pilot.  Reset can be toggled whenever the robot is not moving
without consequence (obviously, brainstem state (including wheel odometry)
is lost).  There is also a separate reset command (brainstem-reset) that
works independently.  This command is now called in the pilot-wrapper.sh
script before pilot is (re)started.

  * GNUmakefile.in: new target `brainstem-reset'.

  * garcia-pilot.cc: not much.

  * garciaUtil.cc: the brainstem_reset function.

  * garciaUtil.hh: prototypes...

  * pilot-wrapper.sh: call brainstem-reset (NOTE: this always fails the
    first time, and I'm not sure why.  It always succeeds subsequently...
    so it makes no difference at the moment).

  * brainstem-reset.cc: new command to reset the brainstem modules.

a name with the stack. Get the leader name from the switch_stack types
table.

initialize a new Nortel stack.

switches that don't need to have them.

We always create VLANs on the leader, though, so that it can be used
as a sort of global list of what VLANs are available, and is
atomically lockable.

Makes some changes to the private VLAN code which are not yet well
tested - but that's okay, because no one uses private VLANs right now.

actually reached their destinations, duh.

the time, and does not get a wiki account.

The reason for these changes is that we are making elabman a real
daemon user so that Tim can run the repositioning daemon as a real
user that can access the XMLRPC server.

distance_remaining for reposition_status.

Initial checkin of a "repositioning" daemon that moves robots back to
their pens on swapout.

	* configure, configure.in: Add tbsetup/repos_daemon.

	* db/libdb.pm.in: Add constants for the
	repositionpending/repositioning experiments.

	* db/nfree.in: When freeing garcias, send them to
	repositionpending instead of reloadpending.

	* event/sched/event-sched.c: Deal with the rare case of no
	SIMULATOR object being in the agent list for an experiment.

	* robots/emc/emcd.c, robots/emc/locpiper.in: Fix some typos.

	* robots/rmcd/masterController.h, robots/rmcd/masterController.c,
	robots/rmcd/obstacles.h, robots/rmcd/obstacles.c: Ignore dynamic
	obstacles that are far away and remove dynamic obstacles where the
	robot is inside the natural obstacle area.

	* sql/database-create.sql, sql/database-migrate.txt: Add a
	reposition_status table that tracks the status of robots that are
	being moved back to their pens.

	* tbsetup/GNUmakefile.in: Install the repos_daemon script.

	* tbsetup/reload_daemon.in: Move robots to the repositionpending
	experiment, if they haven't already reached their pen.

	* tbsetup/repos_daemon.in: Daemon that takes care of seeing robots
	back to their pens after they are freed from an experiment.

Garcia-pilot updates:

	* robots/primotion/buttonManager.hh,
	robots/primotion/ledManager.hh: Comments.

	* robots/primotion/dashboard.hh, robots/primotion/dashboard.cc:
	Turn off fault detection for now, it doesn't work with moving in
	curves at the moment.  Reenable sensor value polling, but only
	while the robot is stationary.

	* robots/primotion/garcia-pilot.cc: Change the handleCallbacks and
	select timeouts to 5ms.

	* robots/primotion/wheelManager.hh,
	robots/primotion/wheelManager.cc: Lower the ranger thresholds when
	movements are short in length.  This should help us maneuver into
	tighter areas, like the robot pens.

* Add a packet capture mode (-c) option so that pcapper can be used
  the same way that tcpdump is used, to write captured packets to an
  output file. When using capture mode, stats are not collected or spit
  out. I need to think about how feasible it is to do both at once; it
  started to look like a mess.

  I added a snaplen (-l) option to be used with capture mode, to
  specify the snaplen that is passed to the pcap library.

* Beef up the event interface, adding a TRACEINFO event type, so that
  you can send START, STOP, KILL events to the pcapper. So, you can
  start and stop packet capture for a link/lan, or for a single node
  on a link/lan (much the same way as you acn control the delay
  agent).
