1.3.37.jcn2
===========

* Fixed srcdir build, so that you can do:

      tar xzf releases/lilypond-x.y.z
      mkdir <build>
      cd <build>
      ../lilypond-x.y.z/configure
      make

  as with any other gnu package.  All build output goes to <build>/out.

* Changed and fixed use of different configurations, and different output
  directories.  Finally, you can use different configurations alongside
  eachother.  From make/stepmake.make:

      # Use alternate configurations alongside eachother:
      #
      #     ./configure --enable-configsuffix=debug
      #     make conf=debug
      #
      # uses config-debug.make and config-debug.h; output goes to out-debug.
      #

      # Use same configuration, but different output directory:
      #
      #     make out=WWW
      #
      # uses config.make and config.h; output goes to out-WWW.
      #
