[Qgis-developer] Processing & SAGA 2.2.2

[Filipe Dias]

Would it be possible/reasonable for QGIS repositories to provide the
supported versions of SAGA alongside QGIS? This issue comes up often and it
seems to consume a lot of the Processing developer's time (which seems to
be very limited at the moment).
Cheers
