If you have installed a 2.x version of man please do the folling things
before updating:

   1. Go to Workbench:Utilities and delete the file 'Man'.
   2. Go to Workbench:WBStartUp and delete the file 'ManCom'.
   3. Double click the install-icon.

This is neccesary because the new 3.x version of 'Man' does only consist
of one file which replaces the old ones.
