Just that we need a different check. For example executing it with the --help 
option and not geting errors.

Good move. Put the real check on the TODO for later.

I do not see the problem with that but it's ok. Indeed i would use a 
completely different extension for both as we are going to put the aggregator 
in 'IgnoreCache' mode at the end.

Did you deleted previous pools? For me it crashed until i delete the old pools 
and regenerated again because some of the attributes have changes. There is a 
serious bug to put in the TODO about that. If you change the schema and load 
an old pool Annotator crashes with an Schema::Exception that should be 
catched and managed.

Also a number of bugs have poped up. For example, when you load a second song 
the InstantViews doesn't update.

We should write down those bugs into the wiki with detailed reproduction steps 
in order to address them before the release.
