[CONFIG]: KEY="VALUE" [...]
a number of configuration options saved between runs in the """ + conf_filename + """ file
erase """ + conf_filename + """ to start with default settings again

CC (default gcc)
CXX (default g++)
	Specify C and C++ compilers (defaults gcc and g++)
	ex: CC="gcc-4.1"
	You can use ccache and distcc, for instance:
	CC="ccache distcc gcc-4.1" CXX="ccache distcc g++-4.1"

JOBS (default 1)
	Parallel build

BUILD (default debug)
	Use debug-all/debug/release to select build settings
	ex: BUILD="release"
	debug-all: no optimisations, debugging symbols
	debug: -O -g
	release: all optimisations, including CPU target etc.
	release-test: mostly release, plus debugging and various things to help crash report analysis

BUILD_ROOT (default 'build')
	change the build root directory

TARGET_SCRIPT (default 0, saved)
	Produce a compiled scripts shared object

SCRIPT_SOURCE (default '~/.etqw/base/src', saved)
	Point to the directory in which the compiled scripts source resides
	You can point to a tarball, which will get expanded, and subsequent zips inside it will be expanded as well

SCRIPT_FOLDER (saved)
	Give a folder name in the expanded tarball so we can have a single tarball with compiled script source for multiple versions (branches support)

NOCONF (default 0, not saved)
	ignore site configuration and use defaults + command line only

SILENT ( default 0, saved )
	hide the compiler output, unless error
"""

if ( not g_sdk ):
	help_string += """
DEDICATED (default 0)
	Control regular / dedicated type of build:
	0 - client
	1 - dedicated server
	2 - both

TARGET_CORE (default 1)
	Build the core

TARGET_GAME (default 1)
	Build the game code

TARGET_MONO (default 0)
	Build a monolithic binary

GL_HARDLINK (default 0)
	Instead of dynamically loading the OpenGL libraries, use implicit dependencies
	NOTE: no GL logging capability and no r_glDriver with GL_HARDLINK 1

ID_NOLANADDRESS (default 0)
	Don't recognize any IP as LAN address. This is useful when debugging network
	code where LAN / not LAN influences application behaviour
	
ID_MCHECK (default 2)
	Perform heap consistency checking
	0: on in Debug / off in Release
	1 forces on, 2 forces off

SETUP (default 0, not saved)
    package release configuration binaries into the bin/ directory
	( can use BUILD=release and BUILD=release-test )
	if TARGET_GAME == 1, compile and create the game pak
	if TARGET_CORE == 1, compile and process the core binaries
	if SETUP == 2, assemble the data into a setup (wether we compile anything new depends on above settings)

SDK (default 0, not saved)
	build an SDK release

NOCURL (default 0)
	set to 1 to disable usage of libcurl and http/ftp downloads feature

BETA (default 0)
	1 or public: enable public beta build
	2 or private: enable private beta build

DEMO (default 0)
	set to 1 for demo build (implies BETA=0 RANKED=0)

RANKED (default 0)
	set to 1 to enable ranked dedicated server build
