Notes from Brett Lee in email 3/27/13
...provide more verbose explanations to the options available to the commands. For example, I think it may be the“lctl list_param –R” that lists all the parameters. It would be great to know which of these are valid (implemented, still supported, etc.) for each version (or at least the version of the manual). Then there are other settings available, like the client, server and network tuneables, and there’s not much explanation of what each does. So, expanding the amount of information about the “details” within Lustre would be my vote for the second thing.

Man pages (code changes) will need to be updated as well.
