Since the problem I encountered involves using Ghostview, which I don't
think was intended in the native Windows distribution of LilyPond 2.6, I
don't think this qualifies as a LilyPond bug. If I'm wrong about that
assumption, please tell me; I'm new to this list and I welcome your
guidance on the way I try to use it.
As noted in two previous posts, LilyPond 2.6 for Windows produces
a .PS file, not a .PDF file. This seems advantageous, as
.PS files are human-readable (to some extent), and they can be
converted anyway.
I installed LilyPond 2.6 running directly under Windows 98SE. I ran
LilyPad, which came up with the Welcome to LilyPond .ly file. I saved the
file, dragged and dropped its icon onto the LilyPond icon; this produced
an (extremely large -- 684 K) .PS file.
