   4 # Dieses Skript erzeugt Differenzbilder (diff) für die
   5 # Patgen-Eingabelisten zwischen zwei angegebenen Commits.  Wird nur ein
   6 # Commit angegeben, wird als Zielcommit "master" verwendet.  Die
   7 # Ausgabedateien werden als Dateien
   8 #
   9 #   dehyph*-x/<Start-Commit-Hash>-<Ziel-Commit-Hash>.diff
  10 #
  11 # in Verzeichnissen gespeichert, die der jeweiligen Rechtschreibung
  12 # entsprechen.  Start- und Ziel-Commit können in jeder gültigen
  13 # Git-Syntax angegeben werden.  Für die Dateinamen werden die
  14 # entsprechenden abgekürzten alphanumerischen Commit-Hashes
  15 # verwendet.
  16 #
  17 # Aufruf:  sh patgen-list-diff.sh <start commit> [<ziel commit>]

  19 #
  20 # Eingabe:  <start commit>      Ein Start-Commit.
  21 #           <ziel commit>       Ein optionaler Ziel-Commit.
