Is the license field here alright? Here's what the LICENSE file has to
say:

> This software can be distributed and used under any of the following
> licenses:
> 
> 	CPL
> 	public domain
> 	BSD (3 clause -- no advertising clause)
> 	LGPL (2.1)
> 	GPL (2)
> 
> in rough order of author preference.
> 
> The CPL is probably unique to this package, and is described here:
> http://www.cypherspace.org/CPL/; if you can't be bothered to figure it
> out feel free to use one of the other licenses.  Earlier versions
> where distributed just under CPL.  CPL allows you to re-license under
> a license of your choice, I just include other specific licenses to
> save people having to read, understand and feel confident in the
> validity of the CPL.
> 
> NOTE: on systems without a POSIX getopt this package will be linked
> with the included getopt.c which is distributed under GPL 2.
