Setting font families for entire document in LilyPond version 2.18.2.

Setting font families for entire document in LilyPond version 2.18.2.

1. I have put solution to template which has been not in the same
directory, according to manuals:

\paper {
  #(define fonts
    (make-pango-font-tree "Times New Roman"             % roman
                          "Nimbus Sans"                 % sans
                          "Luxi Mono"                   % typewriter
    (/ staff-height pt 20)))
}

2. Effect has been for template file:

GUILE signaled an error for the expression beginning here
#
  (define fonts

3. I have put the solution inside a piece, not in template, and effect
was perfect.
4. I have put the solution to template which has been in the same
directory, and effect was perfect, too.
5. So, bug is this: setting font families for entire document does not
work when template is not in the same directory.
6. It is important, because entire document, like books, can have meny
pieces (i.e. 500, like in song books).
7. So, please, find a solution to put templates in any directory for
setting entire document font families.
