This chapter describes the functions provided by the Caml Light standard library. Just as the modules from the core library, the modules from the standard library are automatically linked with the user's object code files by the camlc command. Hence, the globals defined by these libraries can be used in standalone programs without having to add any .zo file on the command line for the linking phase. Similarly, in interactive use, these globals can be used in toplevel phrases without having to load any .zo file in memory.
Unlike the modules from the core library, the modules from the standard library are not automatically ``opened'' when a compilation starts, or when the toplevel system is launched. Hence it is necessary to use qualified identifiers to refer to the functions provided by these modules, or to add #open directives.
