+# This is a shared library or an executable, so computing dependencies properly is
+# crucial. The general rule to apply is the following:
+#
+#   - collect the list of all static libraries that need to be part
+#     of the link, and in the right order. To do so, get the transitive
+#     closure of LOCAL_STATIC_LIBRARIES and LOCAL_WHOLE_STATIC_LIBRARIES
+#     and ensure they are ordered topologically.
+#
+#  - collect the list of all shared libraries that need to be part of
+#    the link. This is the transitive closure of the list of
+#    LOCAL_SHARED_LIBRARIES for the module and all its dependent static
+#    libraries identified in the step above. Of course, need to be
+#    ordered topologically too.
+#
+#  - add Make dependencies to ensure that all these libs are built
+#    before the module itself too.
+#
+# A few quick examples:
+#
+#    main.exe -> libA.a -> libB.a -> libfoo.so -> libC.a
+#
+#      static_libs(main.exe) = libA.a libB.a  (i.e. no libC.a)
+#      shared_libs(main.exe) = libfoo.so
+#      static_libs(libfoo.so) = libC.a
+#
+#    main.exe -> libA.a ---> libB.a
+#                  |           ^
+#                  v           |
+#                libC.a  ------
+#
+#      static_libs(main.exe) = libA.a libC.a libB.a
+#             (i.e. libB.a must appear after all libraries that depend on it).
