How to create a pgn opening database ?

Does anyone know how to create a pgn opening database limited by say 8 moves from a raw pgn file ?

Thanks Steve but I know how to make an opening book. I want to make a pgn database I can limit to a set number of moves. It is more like a silver, Nunn or Noomen opening suite. A cbh database with the same characteristics is interresting also

My bad, didn't see that.

Thanks that is similar to the above. I cant run the gui version as my Av does not like it but perhaps the command line version will work
