| 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|. |
