	${ME} <installer options>

	Valid <installer options> are:

	   --install /PATH/TO/INSTALL

			If your give: --install /opt
			netdata will be installed in /opt/netdata

	   --dont-start-it

			Do not (re)start netdata.
			Just install it.

	   --dont-wait

			Do not wait for the user to press ENTER.
			Start immediately building it.

	   --zlib-is-really-here
	   --libs-are-really-here

			If you get errors about missing zlib,
			or libuuid but you know it is available,
			you have a broken pkg-config.
			Use this option to allow it continue
			without checking pkg-config.

	Netdata will by default be compiled with gcc optimization -O3
	If you need to pass different CFLAGS, use something like this:

	  CFLAGS="<gcc options>" ${ME} <installer options>

	For the installer to complete successfully, you will need
	these packages installed:

	   gcc make autoconf automake pkg-config zlib1g-dev (or zlib-devel)
	   uuid-dev (or libuuid-devel)

	For the plugins, you will at least need:

	   curl nodejs

	Welcome to netdata!
	Nice to see you are giving it a try!

	You are about to build and install netdata to your system.

	It will be installed at these locations:

	  - the daemon    at ${NETDATA_PREFIX}/usr/sbin/netdata
	  - config files  at ${NETDATA_PREFIX}/etc/netdata
	  - web files     at ${NETDATA_PREFIX}/usr/share/netdata
	  - plugins       at ${NETDATA_PREFIX}/usr/libexec/netdata
	  - cache files   at ${NETDATA_PREFIX}/var/cache/netdata
	  - db files      at ${NETDATA_PREFIX}/var/lib/netdata
	  - log files     at ${NETDATA_PREFIX}/var/log/netdata
	  - pid file      at ${NETDATA_PREFIX}/var/run

	This installer allows you to change the installation path.
	Press Control-C and run the same command with --help for help.

		Sorry! This will fail!

		You are attempting to install netdata as non-root, but you plan to install it
		in system paths.

		Please set an installation prefix, like this:

			$0 ${@} --install /tmp

		or, run the installer as root:

			sudo $0 ${@}

		We suggest to install it as root, or certain data collectors will not be able
		to work. Netdata drops root privileges when running. So, if you plan to keep
		it, install it as root to get the full functionality.

NONROOTNOPREFIX
		exit 1

		cat <<-NONROOT

		IMPORTANT:
		You are about to install netdata as a non-root user.
		Netdata will work, but a few data collection modules that
		require root access will fail.

		If you installing permanently on your system, run the
		installer like this:

			sudo $0 ${@}

		Sorry, you do not seem to have autotools 2.60 or later, which is

		You can either install a suitable version of autotools and automake
		or download a netdata package which does not have these dependencies.

		Source packages where autotools have already been run are available
		here:
			   https://firehol.org/download/netdata/

		The unsigned/master folder tracks the head of the git tree and released

	^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

	Sorry! NetData failed to build...

	You many need to check these:

	1. The package uuid-dev (or libuuid-devel) has to be installed.

	   If your system cannot find libuuid, although it is installed
	   run me with the option:  --libs-are-really-here

	2. The package zlib1g-dev (or zlib-devel) has to be installed.

	   If your system cannot find zlib, although it is installed
	   run me with the option:  --libs-are-really-here

	3. You need basic build tools installed, like:

	   gcc make autoconf automake pkg-config

	   Autoconf version 2.60 or higher is required.

	If you still cannot get it to build, ask for help at github:

	   https://github.com/firehol/netdata/issues
