[Haskell-cafe] ANN: permutation-0.2

[Patrick Perry]

Hi Everyone,

I've uploaded a new version of the permutation library to hackage.   
Here is the package description:

     This library includes data types for storing permutations.  It
     implements pure and impure types, the latter which can be modified
     in-place.  The main utility of the library is converting between
     the linear representation of a permutation to a sequence of swaps.
     This allows, for instance, applying a permutation or its inverse
     to an array with O(1) memory use.
     .
     Much of the interface for the library is based on the permutation
     functions in the GNU Scientific Library (GSL).

Here's the url:
