   5         This simple script allows you to encrypt you webpages/etc.
   6         using EncFS (you need to have EncFS installed of course).
   7
   8         You need write permissions to mountpoint for www server
   9         and maybe add www server's user to the fuse group:
  10
  11         gpasswd fuse -a www-data
  12         or
  13         gpasswd fuse -a http
  14
  15         If you want this script to mount EncFS to be accessible by
  16         other users, you can add user_allow_other to /etc/fuse.conf
