package etc

// This file implements module types that install prebuilt artifacts.
//
// There exist two classes of prebuilt modules in the Android tree. The first class are the ones
// based on `android.Prebuilt`, such as `cc_prebuilt_library` and `java_import`. This kind of
// modules may exist both as prebuilts and source at the same time, though only one would be
// installed and the other would be marked disabled. The `prebuilt_postdeps` mutator would select
// the actual modules to be installed. More details in android/prebuilt.go.
//
// The second class is described in this file. Unlike `android.Prebuilt` based module types,
// `prebuilt_etc` exist only as prebuilts and cannot have a same-named source module counterpart.
// This makes the logic of `prebuilt_etc` to be much simpler as they don't need to go through the
// various `prebuilt_*` mutators.
