  Description     : Parse flags, environment variables and config files

 Flag is a drop in replacement for Go's flag package with the addition to
 parse files and environment variables.

 This library is a drop-in replacement of Go's native flag package that
 supports the third factor twelve-factor app methodology: storing the
 config in the environment.

This is a dependency of Shoelaces (#905723) and will be maintained under
the Go team umbrella.
