extending @Book?

[Darrin Smart]

Hi All,

I'm having a little trouble extending the book package. I want to make a
definiton that takes some values and evaluates to a @Section that I can use in
my book. If I put this in mydefs:

extend @Book
def @Test
{
  This is a test
}

I get the error "extend symbol @Book not in scope". Same thing happens if I use
import instead of extend. I can successfully import @DocumentLayout but this is
not useful because I was to use a @Section symol inside my defintion.

Any pointers greatly appreciated! Maybe this could go in the FAQ.

Thanks.
