## Summary

This chapter gave an overview of the different Objective CAML libraries presented as a set of simple modules (or compilation units). The modules for output formatting (`Printf`), persistant values (`Marshal`), the system interface (`Sys`) and the handling of exceptions (module `Printexc`) were detailed. The modules concerning parsing, memory management, system and network programming and light-weight processes will be presented in the following chapters.
