# install.sh - make the https-ssh commands available in every terminal.
#
# Installs three symlinks into the first writable directory that is already on
# PATH (/usr/local/bin, ~/.local/bin or ~/bin):
#
#     https-ssh          the server / gateway and client CLI
#     https-ssh-client   the interactive "connect over HTTPS" helper
#     hsc                short alias for https-ssh-client
#
# Run as your normal user; sudo is only used if /usr/local/bin needs it.
