+
+Base is a complete and portable alternative to the OCaml standard
+library.  It provides all standard functionalities one would expect
+from a language standard library.  It uses consistent conventions
+across all of its module.
+
+Base aims to be usable in any context.  As a result system dependent
+features such as I/O are not offered by Base.  They are instead
+provided by companion libraries such as
+@url{https://github.com/janestreet/stdio, stdio}.")
