Sort out the licence: I've settled on the LGPL.

 LICENCE
 -------
 
-This software is Open Source, but I've not yet decided exactly what
-licence to use.  Be good.  Assume I'm going with the GPL (most
-restrictive) until I say otherwise.  For what it's worth, I think the
-most likely licence is the LGPL (GNU's Lesser General Public Licence)
-which lets you deploy cql-java as a part of a non-free larger work.
+The cql-java suite is Free Software, which is legally -- though not
+morally -- equivalent to Open Source.  See
+       http://www.gnu.org/philosophy/free-software-for-freedom.html
+for a detailed if somewhat one-sided discussion of the differences,
+and particularly of why Free Software is an important idea.
+
+cql-java is distributed under version 2.1 of the LGPL (GNU LESSER
+GENERAL PUBLIC LICENSE).  A copy of the licence is included in this
+distribution, as the file LGPL-2.1.  This licence does not allow you
+to restrict the freedom of others to use derived versions of cql-java
+(i.e. you must share your enhancements), but does let you deploy
+cql-java as a part of a non-free larger work.
