This library allows an application to extend the 'global state' hidden inside the io monad with semi-arbitrary data. data is required to be typeable. the library provides an essentially unbounded number of key-value stores indexed by strings, with each key within the stores also being a string.

this package provides a library for the haskell programming language, compiled for profiling. see http://www.haskell.org/ for more information on haskell.
