Lilypond in MikTeX

[Helge Kruse]

Hello,

I tried the LaTeX example from the Lilypond manual and ran it with MikTeX on 
Windows XP.

Unfortunately LaTeX doesn't know lilypond at all.

   ! LaTeX Error: Environment lilypond undefined.

   See the LaTeX manual or LaTeX Companion for explanation.
   Type  H <return>  for immediate help.
    ...

   l.3 \begin{lilypond}

Does anybody know how to fix this?

Best regards,
Helge
