| You are building Firefox for Android. After your build completes, you |
| should run `mach gradle-install` to prepare Gradle and IntelliJ/Android Studio |
| integration. Then import the Gradle project at $OBJDIR/mobile/android/gradle |
| into the IDE of your choice. |
| |
| PLEASE BE AWARE THAT GRADLE AND INTELLIJ/ANDROID STUDIO SUPPORT IS EXPERIMENTAL. |
| You should verify any changes using |mach build|. |

| |
| Contrary to config.status, it doesn't use CONFIG_FILES or CONFIG_HEADERS |
| variables. |
| |
| Without the -n option, this program acts as config.status and considers |
| the current directory as the top object directory, even when config.status |
| is in a different directory. It will, however, treat the directory |
| containing config.status as the top object directory with the -n option. |
| |
| The --recheck option, like with the original config.status, runs configure |
| again, with the options given in the "ac_configure_args" subst. |
| |
| The options to this function are passed when creating the |
| ConfigEnvironment. These lists, as well as the actual wrapper script |
| around this function, are meant to be generated by configure. |
