+# Privilege Groups
+
+Allows granting and modifying of privs in bulk
+
+Note: only the /grant and /group add behaviour currently exist.
+
+## Usage
+
+By default, a group called "member" is created which has everything in default_privs.
+You can see its properties like so:
+
+	/group info member
+
+Groups can be created or expanded like so:
+
+	/group add groupname privs
+
+Groups are then granted to users like so:
+
+	/grant username groupname
+
+If the caller has the appropriate privileges to grant and privileges in the group,
+then this will cause the player to enter the group and be granted all its privs.
+
+You can remove privs from a group like so:
+
+	/group remove groupname privs
+
+This will remove that priv from any members of that group.
