Thanks for you prompt reply Thomas,
The wiki is more clarifying now that you added the part of the Modes. However,
if I may, I have a couple of remarks to mention:
- For mere consistency of the page, you might want to use the tag <tt> (used in
the rest of the document) instead of the <em> that you are using for names of
files and configuration properties.
- I don't know if this is only my problem, but when I execute Hama with the
Local configuration, the Master doesn't run (and neither does the Groom). They
don't recognize "local" as a valid hostname, both fail with this exception:
From bspmaster.log:

I've tested it in Debian, Ubuntu and MacOS Terminal. Is this maybe a problem
with version 0.3? Would you suggest me to use 0.2 instead?
I'm copying this to the user mailing list too, hope you don't mind.
Luis
