| # fx clean | |
| clean the current Fuchsia build artifacts | |
| ```none | |
| Delete the contents of the output directory except for args.gn and | |
| create a Ninja build environment sufficient to regenerate the build. | |
| This is equivalent to running `gn clean` on FUCHSIA_BUILD_DIR, then | |
| invoking `fx gen` to regenerate critical build files. | |
| ``` | |
