  39 /* This is one of several classes that are nearly identical. Maybe we
  40    should have a central template and generate all these files. This
  41    is one of the cases where templates or macros would have been
  42    useful to have in Java.
  43
  44    This file has been created using search-replace. My only fear is
  45    that these classes will grow out-of-sync as of a result of changes
  46    that are not propagated to the other files. As always, mirroring
  47    code is a maintenance nightmare.  */
