documentation doesn't give unmounting instructions

Binary package hint: gmailfs

Hi all,
        gmailfs documentation is provided by 2 means, one is in /usr/share/doc/gmailfs which is a README which is very very old as well the mount.gmailfs command both of which don't give any instructions how to unmount the mounted partition. Let's say there's a user A, who after following instructions, mounted gmailfs at some mount point. Now normally people use something like synaptic or something so they wouldn't come to know you have to unmount it in a specific way & so on & so forth. Only after which you should uninstall gmailfs.
