[Philipp Wieder]

Dear All,

please find the final version of the GSA use case document at

https://forge.gridforum.org/projects/gsa-rg/document/GridSchedulingUseCasesV1.7.pdf/en/1.

You find the history of the document also on GridForge, just check the

https://forge.gridforum.org/docman2/ViewCategory.php?group_id=133&category_id=714

folder.

I would like to send it to the GGF editor before GGF 16, therefore if 
people want to comment on it, please do it soon.

Best regards, Philipp.
