 """Writes dependency ordered list of native libraries.
 
 The list excludes any Android system libraries, as those are not bundled with
 the APK.
 
 This list of libraries is used for several steps of building an APK.
 In the component build, the --input-libraries only needs to be the top-level
 library (i.e. libcontent_shell_content_view). This will then use readelf to
 inspect the shared libraries and determine the full list of (non-system)
 libraries that should be included in the APK.
 """
 
 # TODO(cjhopman): See if we can expose the list of library dependencies from
 # gyp, rather than calculating it ourselves.
