Getting full custom-bib functionality

Hi there,

I'm in the middle of putting the full functionality of Custom-bib into
Bibulus.  While doing so, I've found a lot of minor differences in the
formatting of various entries.  Many of these might be bugs in
Custom-bib, but they might also reflect desirable features.

However, I'm going to simplify it a bit, so I think a lot of testing
will be needed.

I was wondering if anybody here feels like writing a small program
that will generate all possible combinations of lines in BibTeX.

What I mean is that if entry type X has obligatory AUTHOR and TITLE
and non-obligatory NOTE and EDITOR, four entries should be generated:

@X {ENTRY1,
    AUTHOR = "Some Author",
    TITLE = "Some Title",
}
@X {ENTRY2,
    AUTHOR = "Some Author",
    TITLE = "Some Title",
    NOTE = "Some note",
}
@X {ENTRY3,
    AUTHOR = "Some Author",
    TITLE = "Some Title",
    EDITOR = "Some Editor",
}
@X {ENTRY4,
    AUTHOR = "Some Author",
    TITLE = "Some Title",
    NOTE = "Some note",
    EDITOR = "Some Editor",
}

This will also be very useful for finding bugs in bib2xml.

Any takers?

Cheers,

Thomas
