   3     MoinMoin - Show Ames
   4 
   5     This macro is used to show correct data submission of ames files
   6     using a table showing some info of the file.
   7 
   8     comment: developed in 1.7, not ported to the macro parser yet, because
   9              compatibility to 1.5.8 / 1.6 is wanted.
  10 
  11     dependency: needs the nappy package from
  12                 http://home.badc.rl.ac.uk/astephens/software/nappy
