     12 # When targets depend on, e.g. //content/public/browser, what happens? To
     13 # facilitate the complexity here, the "public" targets are groups that forward
     14 # to the right thing depending on the build mode. Say for additional
     15 # illustration, the public browser sources also depend on the public common
     16 # ones.
     17 #
     18 # The non-component build is easy:
     19 # foo ->
     20 #   //content/public/browser (group) ->
     21 #     //content/public/browser:browser_sources (source set) ->
     22 #       //content/browser (source set, this is the non-public browser target)
     23 #       //content/public/common:common_sources (source set)
     24 #
     25 # The component build is more complicated because we want everybody to depend on
     26 # one content shared library regardless of which public target they depend on:
     27 # foo ->
     28 #   //content/public/browser (group) ->
     29 #     //content (shared library) ->
     30 #       //content/public/browser:browser_sources (source set) ->
     31 #         //content/browser (source set; this is the non-public browser target)
     32 #         //content/public/common:common_sources (source set)
     33 #
     34 # That the internal content dependencies must depend on the *_sources targets
     35 # to avoid dependency cycles, and external dependencies must depend on the
     36 # //content/public/browser and similar targets to avoid double-linking (these
     37 # targets make sure the dependency goes through the content shared library
     38 # when doing a component build).
