# Install files and directories required by treatment (speaker driver software).
# This can also create a dhcpcd.enter-hook for setting the MAC address.
# MA and DK can be passed to Make if it is for a hard (first-time) installation:
# 	sudo MA=mac DK=dk make install_hard
# NB: The default (soft) install does not override conf files or set the MAC address.
# USR can also be passsed to customise user under which the code is housed.
