OAR batch scheduler

Hi,

We are using the OAR batch scheduler here (ESRF, Grenoble France). Apparently nobody did the job for this batch scheduler ?

I started to hack on it and faced two issues:
* OAR enforces the script to be passed as a file rather than via pipe (what apparently all other are doing). This creates an additional file and some more management of file ownership.
* OAR does apparently not preserve the environment variables, this means I had to put the authentication tokens into the script file itself (which is a security issue).

Are you interested in a PR on this topic ?

Cheers

Jerome
