Heh, well unless you're actually planning to make this JSON schema, perhaps you
should change these :)

I'm actually using a schema -- just my own format. :) You want me to change the
variable name?

[not at google - send to devlin, 2012/11/13 22:12:05]

Yes I think that would be less confusing. :) perhaps just schema_file (the fact
that the schema is JSON is an implementation detail, in this case)

Done.
