Hello list,

1)
When I use LilyPondTool for running LilyPond, I get an error message, no
pdf is produced (ps is there!).
Running LilyPond directly works as expected.
2)
Running convert-ly from inside LilyPondTool does not work either; again,
running directly is o.k..

Maybe my jEdit plugin configuration is incorrect?
I have:

Path to LilyPond binary: /usr/local/lilypond/usr/bin
LilyPond command: lilypond
convert-ly command: convert-ly
Python executable: python
GhostrScript command: gs

Thank you,
Thomas
