[O] org-babel-lilypond newbie

[Steven Arntson]

I'm a new Lilypond user (and a beginning but dedicated Emacs user),
trying to decide whether to use Frescobaldi or the org based "Arrange
Mode." I think I've got Arrange Mode running, but can't seem to get the
"tangle" command to work. I opened a .ly file I made in Frescobaldi, put
point at the top, and run M-x ly-tangle. The message returned is
"Tangled 0 code blocks from file-ly.ly."

I'm running org 8.2.6, and have evince installed on my system (though I
haven't told org anything about that, specifically).

Thank you!
