	* Worker/Ssh.py: Fix scp user option in Scp class (ticket #152).

2010-02-22 S. Thiell <stephane.thiell@cea.fr>

	* scripts/nodeset.py: Change command syntax: operations are now specified

	any gathering of results (when -b is not used).

	* Task.py: Allow disabling of MsgTree buffering (trac ticket #3) via
	'stdout_msgtree" and 'stderr_msgtree' Task default keywords, useful if we
	don't want MsgTree internal buffering for fully event-based scripts (eg.
	clush without -b). When disabled, any Task method accessing MsgTree data
	like iter_buffers() will raise a new exception (TaskMsgTreeError).

	switching to alternative line mode display (when using -b). Also, sort
	buffers by nodes or nodeset length like clubak (fix trac ticket #54).

2010-02-11 S. Thiell <stephane.thiell@cea.fr>
	
	* Version 1.2 beta 3 released.

	path.

	* scripts/clush.py: Added option --nostdin to prevent reading from
	standard input (fix trac ticket #49).

	* Engine/Factory.py: Disable Engine.EPoll automatic selection as an issue
	has been found with clush when stdin is a plain file (<file redirections).

	task specific dictionary synchronously. Also remove splitlines() where
	MsgTreeElem are returned instead of whole buffer after latest MsgTree
	improvements.

	* scripts/clubak.py: Added clubak utility (trac ticket #47). It provides
	 dshbak backward-compatibility, but always try to sort buffers by nodes or
	 nodeset. It also provides additional -L option to switch to alternative
	 line mode display.

2010-02-09 S. Thiell <stephane.thiell@cea.fr>

	* Worker.py: Updated Task/MsgTree dependencies. Added iter_node_errors()
	method. Added match_keys optional parameter to iter_node_buffers() and
	iter_node_errors(). Added WorkerSimple.error() method (read stderr).
	Added tests.

	* Task.py: Updated MsgTree dependencies. Factorized most tree data's
	access methods.

	* MsgTree.py: Merged Msg and _MsgTreeElem in one class MsgTreeElem. All
