# A `.command` file is double-clickable in Finder, which is the point: the documented
# alternative was pasting `curl ... | sh` into a terminal, and a terminal is the thing
# this product promises its users they will not need.
#
# It does the whole job: installs ferry, points a folder at Ferryman, and opens the
# dashboard. After this the person is in a browser.
#
# On Linux, `chmod +x` it and run it from the file manager, or from a shell if you
# would rather.

# Finder starts a .command in the user's home directory, not beside the file.
