30// basic_code_modules.h: Contains all of the CodeModule objects that
31// were loaded into a single process.
32//
33// This is a basic concrete implementation of CodeModules.  It cannot be
34// instantiated directly, only based on other objects that implement
35// the CodeModules interface.  It exists to provide a CodeModules
36// implementation a place to store information when the life of the original
37// object (such as a MinidumpModuleList) cannot be guaranteed.
