libset-nestedgroups-perl - 0.01-3.1 main

Set::NestedGroups gives an implementation of nested groups,
access control lists (ACLs) would be one example of
nested groups.
.
For example, if Joe is a Manager, and Managers have access to payroll,
you can create an ACL which implements these rules, then ask the ACL
if Joe has access to payroll.
.
Another example, you may wish to track which city, state and country
people are in, by adding people to cities, cities to states, and states
to countries.
.
This module includes some facilities to integrate its data structures
with either files in the local filesystem and with tables in a RDBMS.
