This option is available if you never want non-anonymous users to be able to modify the filesystem.  Since a read-only filesystem for users is almost always not desiriable, the default for this option is yes.  On the other hand, the a-write-permission option is usually set to no, since anonymous users usually shouldn't be uploading or deleting items in the file store.

Examples:

u-write-permission=yes
u-write-permission=no

u-write-permission=yes
