HI,

I am trying to run a batch job on demand and trying to get it works with  
the script/runner command.  
The job will add some informations in the database with dependencies.

So I have the following code but it failed.

son = Son.new  
father.son= metafile  
metafile.carp = false  
metafile.usemfw = false
