Bug#449475: Serious doubts about the distributability of a file

[Vincent Fourmond]

[please CC me and the bug for replies, thanks]

  Hello,

  The package vegastrike (in main) contains two files whose copyright
header is reproduced integrally in this message. It seems to me that
the copyright notices conflict, and effectively render the file not
distributable, but I am not quite sure; if this file is effectively a
derived work from the work copyrighted by the Universtity of North
Carolina, it is not distributable. It all depends on the meaning of
"based on". What do you think ? What should be done ?

  Thanks

      Vincent
