  56. %% modifications do not get overwritten when you install a new release of

  59. %% standard file. You can then easily distribute your modifications by 
  60. %% distributing the modified and renamed copy of the source file, taking 
  61. %% care to observe the conditions in legal.txt; this will ensure that 
  62. %% other users can safely use your modifications.
