npmc output

Hi List,

Can anyone help with further documentation on the npmc output (library npmc). I can't find details in Munzel& Hothorn's paper. Specifically I am looking for differences (wrt interpretation) of the 

p-value 1s: the 1-sided p-value and 
p-value 2s: the 1-sided p-value.

Any help appreciated
Herry
