	  into the repositories?

		Dan Malek <dan at netx4.com> talks about "I work in the
		BitKeeper tree, which is supposed to be the official PPC
		tree and one step away from kernel.org."

	        What or where is the "BitKeeper tree"?

	- Where are the repositories located?

	- Are these repositories closed?  Or, can others see what changes
	  are being made?

	- How long does it take for the kernel changes from these
	  repositories to make it into the offical Linux kernel release?

	- Who are the people involved with the embedded PPC Linux kernel

	      + MPC8240
	      + MPC8260

	      Dan Malek <dan at netx4.com> writes, " I have been working on
	      the kernel almost daily for many years now, and there are
	      few others that do the same."

	      Dan Malek <dan at netx4.com> is involved, but who are the
	      others?  What is the division of labor between Dan and the

	      This is what I have figure out so far:

		Dan Malek
		Seasoned PPC Kernel hacker for 8xx and 82xx
		product and software development consultant
		dan at netx4.com

		Cort Dougan
		cort at ppc.kernel.org

		Grant M. Erickson
		grant at lcse.umn.edu
		PPC Kernel hacker for 4xx

		Wolfgang Denx
		wd at denx.de
		DENX Software Engineering
		Products: LinuxPPC Cross Development Kit (CDK)
		          LinuxPPC for MPC8xx Systems, especially for TQM8xxL Modules

	- Is this a closed community?  Or, can others join the team?

	- If it is an open community, how does one join?  Are there any
	  posted rules?

	- I want to contribute to the process of porting Linux to
	  run on the EST SBC8260 single board computer, but I need to
	  understand how to participate.
