Sorry, these are different.  In the first example, `without charge' modifies
`distribute' (or possibly `copy, modify and distribute').  In the second 
example `without fee' modifies `Permission ... is ... granted'.  It may be
that the author of xengine's licence doesn't know how to write clear 
English and meant to grant permission without charge, but that isn't what
he has actually written.

Since there are many licences which do not allow commercial exploitation,
this is not a distinction that can be ignored. If xengine is meant to be
DFSG free, the licence needs modifying.  As it stands, the licence does not
permit anyone to charge for a CD which includes xengine.


I see from Atsuhito Kohda's message that it is indeed meant to be DFSG free.
Please get the author to change the licence to this:

 Permission to use, copy, modify and distribute this software,
 documentation, images, etc. is granted without charge, provided that
 this comment and the author's name is retained.  The author assumes no
 responsibility for lost sleep as a consequence of use of this software.

or else use the BSD licence, which has exactly the same effect and has the
advantage of being well understood.
