Could we do something to promote convert-ly?

[Jean Abou Samra]

Folks,

I am getting tired at the number of questions of the type
"Why doesn't this work anymore?" which can be answered by
"Just Run convert-ly! (TM)". I suspect that the effort we
put in crafting convert-ly rules is not paying in perceived
backwards compatibility as users don't think about running
convert-ly, or perhaps don't even know about it. Could we
do something to change this?

Some ideas:

- Mention it in release announcements,
- Mention it in the Changes document,
- When the score produces an error and the \version
  statement is for a different minor version number,
  print a warning ("compilation failed and \version
  statement is outdated, did you update syntax with
  convert-ly?" or something like that).

Thoughts?
