How do I use English note names with lilypond-book?

[Jack O'Quin]

I currently have lilypond-2.1.0-2 from Debian testing.

I'd like to use English note names (like `gs' and `af' for G-sharp and
A-flat) in a book I'm starting work on.

It works to add this...

  \begin{lilypond}
    \include "english.ly"
    ...
  \end{lilypond}

But, the \include needs to be repeated for each \begin, \end pair.  Is
there a cleaner way to do it?

Should I just learn the Dutch names?  :-)
