gtkpool licensing

[Josip Rodin <joy@cibalia.gkvk.hr>]

Hi,

I'm going to packaging gtkpool for Debian, and I was wondering about this
part of the gtkpool README file:

  The code for this game is based on code from
  _Java(tm) Game Programming for Dummies(R)_ by
  Wayne Holder and Doug Bell, (I know, I know,
  but it was the only book the library had on
  game programming, so give me a break, OK? :) )

  All the modifications to that code were
  performed by Jacques Fortier (that's me).

If those two people wrote the code that you modified, they have copyright on
it. What is the license of their code? There is no evidence that it is GPL.

Please clarify this ASAP. Thanks.
