perfsonar development work

[Frederic LOUI <>]

Sorry to bother you with that, but as I'm trying to "catch up the train" 
... ;-)
do you have any updated document/recommendation regarding how the 
developers should build perfsonar rpms ?

So, I can figure out what exactly goes wrong when supporting the 
developers ?
Maybe everything is on the wiki ?

Did you test the document with CL-MP and I guess it has worked ?! ;-)

Thnks in advance !
Cheers/Frederic
