+# This python script helps to build tests in intel gpu tools which have cairo and glib
+# dependency. This script downloads cairo, pixman and glib for android
+# Generates android make file to build cairo and tests which have cairo dependency
+# modifies cairo and glib make files to enable the build
+# This script must be run under inetl_gpu_tools/scripts directory
+# Creates new directory "igt_kms_tests" under intel_gpu_tools and puts all required
+# software here. Generates environment file "build_igt.sh" to include Android
+# drm and pci-include paths. This file may need modification depending on drm and
+# pci-include paths in android source
+#
+# Generates "Android.mk" which can build cairo and glib libraries and all tests under
+# intel_gpu_tools/tests which have cairo dependency
+
+# Generate stubs for cairo functions for which no implementation available
+# Generates stubs for _pixman_implementation_create_sse2,
+# cairo_image_surface_create_from_png, cairo_surface_write_to_png,
+# __android_log_print, testdisplay_setup_hotplug, and testdisplay_cleanup_hotplug
+# These functions are either not supported, not used and not required in android
+
+# To build, follow the instructions shown after running this script under
+# intel_gpu_tools/scripts
