+/* apr_dbd_oracle - a painful attempt
+ *
+ * Based first on the documentation at
+ * http://download-west.oracle.com/docs/cd/B10501_01/appdev.920/a96584/toc.htm
+ *
+ * Those docs have a lot of internal inconsistencies, contradictions, etc
+ * So I've snarfed the demo programs (from Oracle 8, not included in
+ * the current downloadable oracle), and used code from them.
+ *
+ * Why do cdemo81.c and cdemo82.c do the same thing in very different ways?
+ * e.g. cdemo82 releases all its handle on shutdown; cdemo81 doesn't
+ *
+ * All the ORA* functions return a "sword". Some of them are documented;
+ * others aren't. So I've adopted a policy of using switch statements
+ * everywhere, even when we're not doing anything with the return values.
+ *
+ * This makes no attempt at performance tuning, such as setting
+ * prefetch cache size. We need some actual performance data
+ * to make that meaningful. Input from someone with experience
+ * as a sysop using oracle would be a good start.
