/* RFC 2087 5.1. QUOTA Response.
Data: quota root name
list of resource names, usages, and limits
This response occurs as a result of a GETQUOTA or GETQUOTAROOT
command. The first string is the name of the quota root for which
this quota applies.
The name is followed by a S-expression format list of the resource
usage and limits of the quota root. The list contains zero or
more triplets. Each triplet conatins a resource name, the current
usage of the resource, and the resource limit.
Resources not named in the list are not limited in the quota root.
Thus, an empty list means there are no administrative resource
limits in the quota root.
Example: S: * QUOTA "" (STORAGE 10 512)
