-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 pretty much legally
+equivalent -- 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 do pretty
+much anything else with it. In particular, you may deploy CQL-Java as
+a part of a non-free larger work.
