16# This tool translates a collection of BUILD.gn files into a mostly equivalent
17# Android.bp file for the Android Soong build system. The input to the tool is a
18# JSON description of the GN build definition generated with the following
19# command:
20#
21# gn desc out --format=json --all-toolchains "//*" > desc.json
22#
23# The tool is then given a list of GN labels for which to generate Android.bp
24# build rules. The dependencies for the GN labels are squashed to the generated
25# Android.bp target, except for actions which get their own genrule. Some
26# libraries are also mapped to their Android equivalents -- see |builtin_deps|.
