| # This section of the file defines empty variables for each of the Pigweed |

| # facades. Instead of GN always halting due to encountering an undefined |
| # variable, GN will only emit an error if something in the build depends on the |
| # empty (but defined) variable. |
| # |
| # All of these should default to empty strings. For target-specific defaults, |
| # modify these variables in a target confiruation file. |
