+config IB
+	bool "Build the OpenWrt Image Builder"
+	depends on !EXTERNAL_TOOLCHAIN
+	default BUILDBOT
+	help
+	  This is essentially a stripped-down version of the buildroot
+	  with precompiled packages, kernel image and image building tools.
+	  You can use it to generate custom images without compiling anything
+
+config IB_STANDALONE
+	bool "Include package repositories"
+	default y if !BUILDBOT
+	depends on IB
+	help
+	  Disabling this option will cause the ImageBuilder to embed only
+	  toolchain and kmod packages while all other ipk archives will be
+	  fetched from online repositories.
