+To add the freeimage tool to the waf file:
+$ ./waf-light --tools=compat15,freeimage
+	or, if you have waf >= 1.6.2
+$ ./waf update --files=freeimage
+
+The wscript will look like:
+
+def options(opt):
+	opt.load('compiler_cxx freeimage')
+
+def configure(conf):
+	conf.load('compiler_cxx freeimage')
+
+	# you can call check_freeimage with some parameters.
+	# It's optional on Linux, it's 'mandatory' on Windows if
+	# you didn't use --fi-path on the command-line
+
+	# conf.check_freeimage(path='FreeImage/Dist', fip=True)
+
+def build(bld):
+	bld(source='main.cpp', target='app', use='FREEIMAGE')
