SetHashVar
A block tag that is used for creating a hash template variable. A hash is a variable that stores many values. You can even nest SetHashVar tags so you can store hashes inside hashes for more complex structures.
Example:
<mt:SetHashVar name="my_hash"> <$mt:Var name="foo" value="bar"$> <$mt:Var name="fizzle" value="fozzle"$> </mt:SetHashVar>
Then later:
foo is assigned: <$mt:Var name="my_hash{foo}"$>
