-$(error Skia now uses the "Gyp" build system. Please see http://code.google.com/p/skia/wiki/DocRoot )
+# Makefile that wraps the Gyp and build steps for Unix and Mac (but not Windows)
+# Uses "make" to build on Unix, and "xcodebuild" to build on Mac.
+#
+# Some usage examples (tested on both Linux and Mac):
+#
+#   # Clean everything
+#   make clean
+#
+#   # Build and run tests (in Debug mode)
+#   make tests
+#   out/Debug/tests
+#
+#   # Build and run tests (in Release mode)
+#   make tests BUILDTYPE=Release
+#   out/Release/tests
+#
+#   # Build bench and SampleApp (both in Release mode), and then run them
+#   make SampleApp bench BUILDTYPE=Release
+#   out/Release/bench -repeat 2
+#   out/Release/SampleApp
+#
+#   # Build all targets (in Debug mode)
+#   make
+#
+# If you want more fine-grained control, you can run gyp and then build the
+# gyp-generated projects yourself.
+#
+# See http://code.google.com/p/skia/wiki/DocRoot for complete documentation.
