+Version 0.1.2:  (2012-08-21)
+  * Added Show constraints for compatibility with recent versions of
+    GHC,  as Show is no longer a superclass of Integral
+
+  * Applied a patch from Melissa O'Neill that fixes the priority queue
+    in her sieve.   This bug does not effect the prime generation
+
 Version 0.1.1:  (2010-09-02)
   * Changed the module naming hierarchy from NumberTheory.* to Math.*

 Description:         This package includes the Sieve of O'Neill and two generalizations of the Sieve of Eratosthenes.   The Sieve of O'Neill is a fully incremental primality sieve based on priority queues.  The other two are array based, and are not incremental.   One sieves the smallest prime factor,  and is useful if you want to factor a large quantity of small numbers.   The other sieves Euler's Totient,  which is the number of positive integers relatively prime and less than a given number.
