- The EUROPAGATE research project working under the Libraries programme
- of the European Commission's DG XIII has, amongst other useful tools,
- implemented a general-purpose CCL parser which produces an output
- structure that can be trivially converted to the internal RPN
- representation of &yaz; (The <literal>Z_RPNQuery</literal> structure).
- Since the CCL utility - along with the rest of the software
- produced by EUROPAGATE - is made freely available on a liberal
- license, it is included as a supplement to &yaz;.
