1.3.130.jcn2
============

////* Changed default output extension to ".lytex".

* Ignore outname = ; settings in output blocks.

* Revised input and output naming, now it's possible to include a
directory in the output name.  This should fix some input/init name
related bugs.

* Fixed dependencies for outdir in lilypond-book and ly2dvi.

* Uniformised tags to read: Generated automatically by: <program>.

* Install make/* and stepmake/stepmake/* to enable making use of
stepmake templates.

* Added example mutopia makefile: make/ly.make.

* Lilypond-book now writes lily-<HASH>.ly files.
