expressions list -> equations list

1st of all THX to all who answered my last question. Just one other before
I lend a Mathematica manual from the public lib and pester you no more :-)

So. Now that I have a tensor it must vanish identically. I Flatten[] it first
and then I have a list of equations...oh, stop, I haven't. REDUCE (if I may
mention the name of a competition :-) could take a Solve[] now because it 
automatically assumes a "=0" as default but Mathematica is anally-retentive
(a good thing :-) and I somehow must turn {a,b,c} into {a=0,b=0,c=0}.
Convert to string, global change "," -> "=0," and "}" -> "=0}", reconvert
to list? Is that possible? Or is there a less LISP-hack-style solution?
