+# Takes as input a "source_set" that includes dependencies that are relative to
+# the parent directory of the Mojo public SDK (given in |mojo_sdk_deps|).
+# Generates a source_set that has the mojo_sdk_deps added as ordinary deps
+# rebased to the current directory.
+# By default, restricts the entries that are given in invoker.deps and
+# invoker.public_deps to be only within the same file and on a small set of
+# whitelisted external dependencies. This check can be elided by setting
+# restrict_external_dependencies to false in the invoker. DO NOT DO THIS in
+# //mojo/public.
+#
+# Example of a mojo_sdk_source_set:
+#
+# mojo_sdk_source_set("foo") {
+#   sources = [
+#     "foo.h",
+#     "foo.cc",
+#   ]
+# 
+#   # Same-file deps are specified in the ordinary way. Any external
+#   dependencies are specified the same way (although in general there should
+#   be very few of these).
+#   deps = [
+#     ":bar",
+#   ]
+# 
+#   # Mojo SDK deps are specified relative to the containing directory of the 
+#   SDK via mojo_sdk_deps.
+#   mojo_sdk_deps = [
+#     "mojo/public/cpp/bindings",
+#     "mojo/public/cpp/environment",
