Opening book in very simple format?

Hello,
I'm looking for opening book in text format used by TSCP engine. It contains one variation per line. Every one written as sequence of moves separated with spaces. I use TSCP book along with my engine but this book is too small. Maybe I can somehow convert another book to this format if there are no books in simple text format available?
