DESCRIPTION="Script to mount a network (e.g. sshfs/davfs) directory and subsequently start keepass with a vault in said directory

Requires 
  - the flatpak version of KeepassXC to be installed (or whatever version is passed via the -c argument)
  - an fstab entry for the desired mount point (using davfs2)"

USAGE="keepass-mounter.sh mount-point db-file [OPTIONS]

  mount-point The directory to mount the remote storage into
  db-file     The path to your keepass vault (relative to the mount point)

  Options:
      -b, --backup  A path for storing a database backup
      -c, --command The command for executing keepass (defaults to the flatpak version of keepass).
                    '--DB_PATH--' will be replaced with the path to the password database.
      -h, --help    Show this help message

Example:
