thanks.
I've added the following to the docs


The expression will be evaluated in the @code{guile-user} module, so
if you want to use definitions in @var{expr}, use

@example
lilypond -e '(define-public a 42)'
@end example

@noindent
on the command-line, and include

@example
#(use-modules (guile-user))
@end example

@noindent
at the top of the @code{.ly} file.
