Nemenyi test post-hoc for Kruskal-Wallis test

[#1]

Is there a way to do post-hoc testing for the Kruskal-Wallis test for non-parametric data? I have searched the web and most use the Nemenyi test as described by Zar in Biostatistical analysis 3rd edition p226. I have a large amount of data and don't want to do all this by hand.

Many thanks
