+ImageGrid.Viewer Makefile...
+
+To print full list of user make targets use:
+	make help
+
+
+Variables to control the build:
+	APP_NAME	- Application name
+	APP_BIN		- App binary name (ignored for MacOS)
+
+	ARCH		- target achitecture (ia32, x86)
+	TARGET_OS	- target OS (win32, linux, darwin)
+
+	ELECTRON_DOWNOAD_URL
+			- URL to download electron binary
+	ELECTRON_DIST	- electron distribution file name pattern
+	BUILD_MODE	- can be "repack" or "in-place" (default)
+
+NOTE: when setting variables avoid using spaces and other characters 
+	make can get fussy about...
+NOTE: to do a repack build call:
+		(export BUILD_MODE=repack && make)
+NOTE: cross compilation is at this time not supported, if you try it 
+	and it works then 1) you got very lucky and 2) tell me about it =)
+	...at least the node native packages (sharp) will likely either 
+	fail or	will get compiled to the wrong arch and not be used and 
+	some non-native packages may misbehave (though I'm not aware of 
+	any at this point, so report them if you encounter one).
+	This is complicated by the fact that most of ImageGrid.Viewer is
+	platform-agnostic and will run on almost anything and will simply 
+	try to ignore broken packages and features depending on them, so
+	check the console log for any odd load reports...
+	...but note that cross-building and packaging is possible either
+	without the native modules or with them pre-built for the target
+	platform.
+
+
+Examples:
+	# check if all dependencies are available...
+	make check
+
+	# full build...
+	make clean dist
+
+	# build for darwin... (XXX needs testing)
+	export TARGET_OS=darwin && make clean dist
+
+
