read/parse this book, in reality it wasn't. It doesn't seem to understand
full pgn format and instead uses an abbreviated format (which all the other

Include a script to convert the book to a proper format and then run gnuchess
across that and it seems to find much less errors.
foo-* to foo-[0-9]*. This is to cause the dependencies to match only the
packages whose base package name is "foo", and not those named "foo-bar".
A concrete example is p5-Net-* matching p5-Net-DNS as well as p5-Net. Also
change dependency examples in Packages.txt to reflect this.
