"lilypond for programmers" untutorial, inviting comments

[Johannes Waldmann]

Dear all,

I thought I should not just ask naively and complain loudly,
but also contribute something. So I made an attempt
at explaining (the basics, as I see them, of) "lilypond for programmers"
http://www.imn.htwk-leipzig.de/~waldmann/etc/untutorial/lilypond/

("un-tutorial" in the sense that it's written by an un-expert,
as opposed to a tutorial written by an expert.)

Comments welcome (off-list email is best for now, I guess) - J.W.
