-I often find it useful to include a date on printed music, so that I
-can see if I'm using the latest version, or tell someone else that he
-should only use the version after a certain date. A simple solution is
-to enter the date manually to the @code{.ly} file. But that's very
-error prone. It's easy to forget updating the date. So i thought it
-would be useful if you can add the date on which the PDF file is
-generated automatically. I did't figure it out myself, but I asked on
-lilypond-user mailing list. And guess what? Someone came with an
-excellent solution! So thank you very much Toine Schreurs for sending
-this solution to the user mailing list. I post it here for future
-reference.
