For those of you who just can't wait for the CVS update the 
outcome of these debates was:


> 	*) resource name, should it be part of the command line.

        No, as everthing else is passed as meta-data.
        That is, as environment variables.

> 	*) monitor action, should it be replaced by a quick-check

        The conclusion was to set three levels of checking.
	I forget the names, but they can be summarised
	as light, medium and heavy. There is room to
	add more as needed. The document goes into
	some detail on what these levels mean.

> 	*) the return codes for monitor, should it be overloaded. 

        The conclusion was no. The reasoning was that overloading it
	could cause unexpected problems in code calling the agents
	(usually scripts) that can do non-obvious things with
	return values. Thus, it is best just to return 0.

	The extra feed back that overloading the return value
	could have given may be added in the future. For instance
	by writing information to stdout.


A nother area of intense debate was the name space for meta-data
(environment variables). The conclusion, by a vote, was that there
would be a name space in the form of prefixing all the variable
names. This is as per the existing draft in CVS. Though the wording
has probably been updated.


The feeling of all present at the end of the meeting seemed
to be very positive. I think everyone present is happy
with the document as it will stand once Lars updates CVS
and are happy for it to move to the next stage - which I believe
is public aprasial of some sort.
