#    rfs_konqueror -- 2 pane konqueror with remote file system

#    Use:
#         $ rfs_konqueror script_name  [directory_name]

#    28-Apr-20 -- First light, Marvin L Jones
#
#    Mount a remote file system and open konqueror with
#    2 panes -- one in the remote fs, one in $HOME/...somewhere.

#    "script_name" is any of several unique bash scripts that
#    mount (sshfs) remote file systems on a unique $HOME/
#    directory for each unique mount.
#    E.g., `vps` is a script to sshfs mount the remote VPS
#    server on $HOME/VPS
#    Likewise `example.net` would be a script to mount the
#    root directory of the website on $HOME/EXAMPLE.NET
#
#    Convention: lowercase script_name corresponds 1-to-1
#    with UPPERCASE mount point in $HOME.
#
#    "directory_name" is an optional directory in $HOME
#    on which the pane for the _local_ directory opens.
#    The default is "$HOME"
#
#    Flow:
#    Mount the remote file system, and cd onto the mount point
#    to prevent it being umount'ed while we're active.
#    Then a dual-pane konqueror profile is built (if not yet
#    existing) specifying the local $HOME/..../ directory
#    and the remote directory.
#    Then konqueror is executed with this profile.
#    When konqueror ends, we cd out of the remote mount point
#    and umount the remote fs.
#    (We leave the profile for possible future use....)
#
#    It is expected that this script will only be executed
#    from desktops objects.  But, command line junquies
#    could make use of it.
