r265:    * It turns out it's possible to set up make variables that are specific to
     a single target of a Makefile. This works tremendously well with
     DH_OPTIONS: no need to put "-i" or "-pfoo" after every debhelper command
     anymore.
   * debhelper.1: mentioned above technique.
   * examples/rules.multi: use the above method to get rid of -i's and -a's.
   * examples/rules.multi2: new file, example of a multi-binary package that
     works for arch-indep and arch-dependant packages, and also allows
     building of single binary packages independntly, via binary-<package>
     targets. It accomplishes all this using only one list of debhelper
     commands.
   * examples/*: removed source and diff targets. They've been obsolete for 2
     years -- or is it 3? No need for a nice error message on failure anymore.
