# Install files and directories required by NetSender clients (such as gpio-netsender, rv, etc.)
# and create a dhcpcd.enter-hook for setting the MAC address.
# MA and DK can be optionally passed to Make, e.g, for a hard (first-time) installation:
# 	sudo MA=mac DK=dk install_hard
# NB: The default (soft) install does not override conf files.
# USR can also be passsed to customise user under which the code is housed.
# For example, if you're trying to make rv on your laptop instead of a pi,
# set USR=<your user name>.
