About Lilypond preprocessor

[CRETEL Dominique]

Hi all,

Someone tell me that a soft named Lilypond was born last year which
vocation is to be a music preprocessor for PMX. Moreover, it is very
simple at use and very friendly.
Is there anybody who can send me some informations about it ? Where can
I find it ? And does it still exist ?

Thanks,
Dominique Cretel.
