    longDescription = ''
      Many computer users need to manipulate text files: extract and then
      operate on data from parts of certain lines while discarding the rest,
      make changes in various text files wherever certain patterns appear,
      and so on.  To write a program to do these things in a language such as
      C or Pascal is a time-consuming inconvenience that may take many lines
      of code.  The job is easy with awk, especially the GNU implementation:
      Gawk.

      The awk utility interprets a special-purpose programming language that
      makes it possible to handle many data-reformatting jobs with just a few
      lines of code.
