The example demonstrates how to use a module summary index file produced for ThinLTO to: * find the module that defines the main entry point * find all extra modules that are required for the build A LIT test runs the example as part of the LLVM test suite [1] and shows how to create a module summary index file. The code also provides two Error types that can be useful when working with ThinLTO summaries.
