11 # Takes as input a "source_set" that includes dependencies that are relative to
12 # the parent directory of the Mojo public SDK (given in |mojo_sdk_deps|).
13 # Generates a source_set that has the mojo_sdk_deps added as ordinary deps
14 # rebased to the current directory.
15 # By default, restricts the entries that are given in invoker.deps and
16 # invoker.public_deps to be only within the same file and on a small set of
17 # whitelisted external dependencies. This check can be elided by setting
18 # restrict_external_dependencies to false in the invoker. DO NOT DO THIS in
19 # //mojo/public.

22 #

30 # dependencies are specified the same way (although in general there should
31 # be very few of these).
