Making a Lilypond donation (again)

[Ivan Kuznetsov]

I would like to make a onetime donation toward
the development of Lilypond.

I have searched the archives of this list, and
over and over again, it has been stated that
there is no clear way to do this.

At https://www.gnu.org/software/, Lilypond
is listed as a "current GNU package", but
can one donate money to GNU/Free Software
Foundation with the money being earmarked
specifically for Lilypond development ?

A few places, it is suggested that since
David Kastrup <dak@gnu.org> is currently
the only full time developer of Lilypond
(is this still true?) and since he has
asked for denotations in the past, that
sending a donation directly to Mr. Kastrup
is one way to go.  Is that what people
are doing?

Thank you for your help.
