	There \does appear to be a license: it is included at the top of 
the main module, i.e: 

;; This program is free software; you can redistribute it and/or modify it
;; under the terms of the GNU General Public License...

The GPL itself is included in several formats in the license directory.  
In what way was the license seen to be missing---is there a particular 
field in the PlaneT system that was blank?
	More generally: maybe my understanding of copyright law is flawed, 
but I thought that licenses were included to \reserve rights.  And if 
someone declines to reserve rights, couldn't you do just about anything 
you want with the code/works in question, short of plagiarizing them and 
claiming them as your own doing?  I thought the purpose of the GPL was to 
\prevent people slightly modifying free software and then charging for 
it, among other things.
