Customizing the Bookreader Display
  Most DECwindows applications provide dialog boxes that
  contain options for customizing your DECwindows environ-
  ment and saving your settings.  However, Bookreader does
  not provide such an option.  To change and save settings in
  Bookreader, you must specify the settings in a resource file.
                                Note
      Use extreme caution when modifying resources.
      DECwindows does not provide error handling for re-
      sources.  Syntax errors in resource files may cause
      DECwindows to fail, without providing error mes-
      sages.
