2. Updating files with convert-ly

As LilyPond is improved, the syntax (input language) of some commands and functions can change. This can result in unexpected errors, warnings or even wrong output when input files, previously created for older versions of LilyPond are then used with later versions.

To help with this the convert-ly command can be used to upgrade these older input files to use the newer syntax.
