Would it be better to have the format more as a CSV

bbfilename,src_uri,srcrev,autorev?

This would make it easier to parse for scripts

Jerrod, you are the requester on this, do you have any comments on the 
format?

Do we really need the extra level of directory here?  Can the data be 
contained in a ${PN}-${PV} file instead?  Also this might be better to 
be ${BP} (base package & version).

You already have the mulitlib info in the ${MULTIMACH_TARGET_SYS} info.


Thanks
