// This protobuf file defines messages used to represent the build flags used by
// a release in a more human-editable form.  It is used for on-disk files in the
// source tree.
//
// The following format requirements apply across various message fields:
//
// # name: name of the flag
//
//    format: an uppercase string in SNAKE_CASE format starting with RELEASE_,
//      no consecutive underscores, and no leading digit. For example
//      RELEASE_MY_PACKAGE_FLAG is a valid name, while MY_PACKAGE_FLAG, and
//      RELEASE_MY_PACKAGE__FLAG are invalid.
//
// # namespace: namespace the flag belongs to
//
//    format: a lowercase string in snake_case format, no consecutive underscores, and no leading
//      digit. For example android_bar_system
//
// # package: package to which the flag belongs
//
//    format: lowercase strings in snake_case format, delimited by dots, no
//      consecutive underscores and no leading digit in each string. For example
//      com.android.mypackage is a valid name while com.android.myPackage,
//      com.android.1mypackage are invalid
