// This module provides access to information Soong has related to the
// whole platform bootclasspath. Currently, that information is provided solely
// through configuration but additional information will be added here.
//
// This will provide support for the following:
// * Hidden API processing for those parts of the bootclasspath that are not
//   part of an APEX.
// * Compatibility checking to ensure that the hidden API bits encoded into the
//   dex files by the modularized hidden API processing is compatible with the
//   runtimes of earlier releases which expect the bits to have been computed
//   over the entirety of the bootclasspath in one go not separately.
// * Dexpreopting apps and other libraries not on the platform bootclasspath.
// * Generating and installing the appropriate files to the device which will
//   allow it to generate the bootclasspath related environment variables
//   dynamically.
//
// This module needs to be present in the build for the above processing to be
// done correctly.
