Subject: [PATCH] * makeWrapper: new function that transparently takes care of
 creating   a wrapper script.  E.g.

    wrapProgram $out/bin/prog --set FOO bar

  will create a wrapper around "prog" so that the environment variable
  FOO is set to bar.  The original program is renamed to
  $out/bin/.wrapped-prog.

* Function makeSetupHook to convert a script into a setup hook which
  can be included in buildInputs.  This makes it easier to use scripts
  like makeWrapper.

* Added Bazaar, yet another distributed version management system.
