A script to mount or unmount your SMEStorage Cloud Provider folders for local access.
The default folder location is 'Downloads/SMEStorage', the location must either not currently exist or be empty.
( Placing it under the 'Downloads' folder allows access from both ChromeOS and your chroot environment. )

This program should first be run from the chroot where SMEStorage is installed and then, optionally, in Crosh.
Also, when unmounting, it should first be unmounted in the chroot and then, optionally, in Crosh.
 
FORMAT: ${Bname} [Folder] [SMES_Username] [SMES_Password]

Options:
        -h      Help - prints this usage summary and exits.
        -u      Unmount 'Downloads/SMEStorage' or the location you specified.

# Function to exit with exit code $1, spitting out message $@ to stderr

  echo "$*" 1>&2
  exit "$ecode"
