I am intending to upgrade to TDE 14 on Wheezy, and then upgrade Wheezy to 
Jessie when the dust has settled and I have had a bit of fun running 14 on 
Wheezy..

Is this the best source, with jessie changed to wheezy?  (I like Slávek's 
repositories and keeping up with patches.)

deb http://mirror.xcer.cz/trinity-sb jessie deps-r14 main-r14

I can't upgrade to Jessie first, because 10.5.13.2 is not available for 
Jessie.

Thanks,
Lisi
