In many cases, it is useful, necessary, or simply nice to limit how
 frequently you perform some action. For example, you may want to limit
 how often your program makes a request of some web site. This library
 is intended as a general-purpose mechanism for rate-limiting IO actions.

 This package provides the documentation for a library for the Haskell
 programming language.
