+/*
+ * This module allows the default quota values,
+ * in the windows explorer GUI, to be stored on a samba server.
+ * The problem is that linux filesystems only store quotas
+ * for users and groups, but no default quotas.
+ *
+ * Samba returns NO_LIMIT as the default quotas by default
+ * and refuses to update them.
+ *
+ * With this module you can store the default quotas that are reported to
+ * a windows client, in the quota record of a user. By default the root user
+ * is taken because quota limits for root are typically not enforced.
+ *
+ * This module takes 2 parametric parameters in smb.conf:
+ * (the default prefix for them is 'default_quota',
+ * it can be overwrittem when you load the module in
+ * the 'vfs objects' parameter like this:
+ * vfs objects = default_quota:myprefix)
+ *
+ * "<myprefix>:uid" parameter takes a integer argument,
+ * it specifies the uid of the quota record, that will be taken for
+ * storing the default USER-quotas.
+ *
+ * - default value: '0' (for root user)
+ * - e.g.: default_quota:uid = 65534
+ *
+ * "<myprefix>:uid nolimit" parameter takes a boolean argument,
+ * it specifies if we should report the stored default quota values,
+ * also for the user record, or if you should just report NO_LIMIT
+ * to the windows client for the user specified by the "<prefix>:uid" parameter.
+ *
+ * - default value: yes (that means to report NO_LIMIT)
+ * - e.g.: default_quota:uid nolimit = no
+ *
+ * "<myprefix>:gid" parameter takes a integer argument,
+ * it's just like "<prefix>:uid" but for group quotas.
+ * (NOTE: group quotas are not supported from the windows explorer!)
+ *
+ * - default value: '0' (for root group)
+ * - e.g.: default_quota:gid = 65534
+ *
+ * "<myprefix>:gid nolimit" parameter takes a boolean argument,
+ * it's just like "<prefix>:uid nolimit" but for group quotas.
+ * (NOTE: group quotas are not supported from the windows explorer!)
+ *
+ * - default value: yes (that means to report NO_LIMIT)
+ * - e.g.: default_quota:uid nolimit = no
