We really need to generate something less embarrassing here. Can we fake it and
say like

The <code>chrome.{{api.name}}</code> API.

I think there's name info somewhere.

Done.

If the availability isn't available, it's probably available. Maybe we should
say "Available". Kind of a cop-out but it's less embarrassing than admitting we
have incomplete docs.

[epeterson, 2013/05/13 02:38:10]

Done. (ha.)

it's nice to close these off with the name of the tag, like HTML. same elsewhere
in this files.

[epeterson, 2013/05/13 02:38:10]

Done.

[not at google - send to devlin, 2013/04/30 18:34:19]

I don't see the point of having this be intro_permissions. Just permissions is
more representative of the API model.

[epeterson, 2013/05/13 02:38:10]

It looks like 'permissions' is already reserved for other data in
api_data_source (used in determining what channel the API is being viewed from,
I think?)
