+Added support for CCL, compiled on the client side, in ZOOM-C. This
+is invoked using ZOOM_query_ccl2rpn(); the resulting query objects can
+be used for for searching with ZOOM_connection_search() and scanning
+with ZOOM_connection_scan1(). Before it can be used for CCL
+searching and scanning, the connection object must be configured by
+setting the "cclfile" option to the name of a CCL qualifier file such
+as the one in "client/default.bib".
+
+YAZ' configure searches for OpenSSL by default.
+
+SSL comstack uses SL_CTX_use_certificate_chain_file rather than
+SL_CTX_use_certificate_file. See
+http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
+for more info. Thanks to Ko van der Sloot.
