* gedit - a graphical text editor

  Commands where an editor is used (rare, but in writing scripts) will
  be given with gedit.  While almost any editor can be used instead, be
  careful to write files in Unix plain text format.

  e.g. on Mac systems, using TextEdit, one should select:
      Format -> Make Plain Text


* Consider buying a book, e.g.
