=============
ADVERTISEMENT
You are building Firefox for Android. After your build completes, you can open
the top source directory in IntelliJ or Android Studio directly and build using
Gradle. See the documentation at
https://developer.mozilla.org/en-US/docs/Simple_Firefox_for_Android_build
PLEASE BE AWARE THAT GRADLE AND INTELLIJ/ANDROID STUDIO SUPPORT IS EXPERIMENTAL.
You should verify any changes using |mach build|.

Visual Studio Support Available
You are building Firefox on Windows. You can generate Visual Studio
files by running:
mach build-backend --backend=VisualStudio

'''Main function, providing config.status functionality.
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 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.
See build/autoconf/config.status.m4.
