gly - alternative Gregorio input format

I would like to announce first release of gly - a modified Gregorio input format separating lyrics from music (in a way similar e.g. to LilyPond) and allowing more than one score per file.

I designed it to fit my needs as "composer" writing on computer. For composition (as opposed to transcription) workflows the default Gregorio GABC isn't very practical and gly attempts to address the most painful issues.

I don't expect everyone will be excited and start using gly, but possibly some of the readers will find it as practical as I do.

Comments are welcome.
