I'm trying to find an explanation of the difference between '=' and '=>'.  I
thought a good first step would be finding out whether this is a Ruby or a Rails
construct.  Then I'd dig in before bothering the list.  No joy at step 1.  Can
anybody point me to the right documentation?

Thanks in advance,
Bill

It's Ruby.

In brief, '=' is a general assignment, while '=>' is specifically for
key-value relationships in hashes.

Theres some documentation here:
