#
# Use sshfs to mount a server's filesystem on this laptop.
# https://osxfuse.github.io/
# * Requires both FUSE and SSHFS
#
# If this script's name is something other than "mount-ssh", the server name
# will be parsed from this script's name. This means you can copy, symlink, or
# hard-link the script to a new name, and that copy will mount that server.
#
# 2017-10-10 jms1 - added `allow_other` option
