   4         This pseduo-header file contains declarations for public symbols that are exported in libsystem_info.dylib but don't have
   5         a proper header file in the Libinfo project. These symbols are typically declared in header files installed by other
   6         projects. The purpose of this file is to allow InstallAPI, which parses header files to infer the symbols exported by a
   7         library, to know about these symbols.
