There is no COPYING file or similar in the tar ball.
We do not know the author and the origin of the dict.
The website http://download.huzheng.org/Quick/ has no reliable information on licenses.
One package is even tagged as
"quick_frank-deu-eng is Commercial, others GPL"
but no license files are present.
There is no reason to believe that we may distribute it properly as GPL.
