* $readGrps is a list of the possible criteria for a request to have
* access to read a container. Each item is one of the following formats:
+ * account:user - Grants access if the request is by the given user
* .r:<regex> - Grants access if the request is from a referrer host that
* matches the expression and the request is not for a listing.
* Setting this to '*' effectively makes a container public.
* matches the expression and the request for a listing.

* access to write to a container. Each item is of the following format:
