convert-ly with lily2.4.2

[Jean-marc LEGRAND]

Hi list !

I've just moved to 2.4.2 on XP, and I'm converting all my files.

I've got 2 pb :

1.  convert-ly -e `find . -name '*.ly' -print` doesn't work, and no error 
message.

2. when I make convert-ly -e fichier.ly, I have à fichier.ly updated but a new 
fichier.ly~ which I
have to erase manually.

Any help ?

Regards
