+# This file helps integrate apitrace into FirefoxOS - when apitrace
+# sources are put in B2GROOT/external/apitrace (including this Android.mk
+# file), then the B2G build system will pick apitrace automatically and
+# compile and install it into the system images seamlessly.
+#
+# This may work in other than FirefoxOS environments, but has not been tested.

+# Below we hook the process of configuring and compiling apitrace,
+# described in INSTALL.markdown (but we use the FirefoxOS's NDK). We override
+# the $(linked_module): targed, which is already defined by
+# $(BUILD_SHARED_LIBRARY) - by default it would want to compile the
+# library out of some source files.
+# We also override the target $(LOCAL_INSTALLED_MODULE): which installs
+# the shared library because we want it installed in
+# /lib/apitrace/wrappers/egltrace.so instead of /lib/egltrace.so because
+# /bin/apitrace searches for the library in that directory.
+# The rules will end up with /lib/apitrace/wrappers/egltrace.so and
+# /bin/apitrace inside system.img.
