Re: AW: [geclipse-dev] PBS implementation

[Romain <reuillon@xxxxxxxx>]

Hi Mathias,

I am working on it right now. I have created a new package in the bundle 
and exposed the SSH tool. I will send a patch to Harald as soon as I 
have a first working version with PBS.

I don't think you had this mail, it was off the mailing list:
