Changes for 0.4
---------------
IMPORTANT: Configuration language changes:

	- "parallel" renamed to "cpus" (other was confusing)

	- "[global]" must be replaced by "[*]": we now process *every*
	  matching section, in order.

Other changes:
	ccontrol-init: better handling for probing distcc hosts
	configuration: "include" keyword for including files
	documentation: clarifications, hacking advice, license
	distribution: include .hg dir to help users become developers
	users: ccontrol now has a second user (and developer)
