+ * page.h contains a detailed description of the page format.
+ *
+ * Normally, keys and data are accessed from offset tables in the top of
+ * each page which point to the beginning of the key and data.  There are
+ * four flag values which may be stored in these offset tables which indicate
+ * the following:
+ *
+ *
+ * OVFLPAGE Rather than a key data pair, this pair contains
+ *      the address of an overflow page.  The format of
+ *      the pair is:
+ *          OVERFLOW_PAGE_NUMBER OVFLPAGE
+ *
+ * PARTIAL_KEY  This must be the first key/data pair on a page
+ *      and implies that page contains only a partial key.
+ *      That is, the key is too big to fit on a single page
+ *      so it starts on this page and continues on the next.
+ *      The format of the page is:
+ *          KEY_OFF PARTIAL_KEY OVFL_PAGENO OVFLPAGE
+ *
+ *          KEY_OFF -- offset of the beginning of the key
+ *          PARTIAL_KEY -- 1
+ *          OVFL_PAGENO - page number of the next overflow page
+ *          OVFLPAGE -- 0
+ *
+ * FULL_KEY This must be the first key/data pair on the page.  It
+ *      is used in two cases.
+ *
+ *      Case 1:
+ *          There is a complete key on the page but no data
+ *          (because it wouldn't fit).  The next page contains
+ *          the data.
+ *
+ *          Page format it:
+ *          KEY_OFF FULL_KEY OVFL_PAGENO OVFL_PAGE
+ *
+ *          KEY_OFF -- offset of the beginning of the key
+ *          FULL_KEY -- 2
+ *          OVFL_PAGENO - page number of the next overflow page
+ *          OVFLPAGE -- 0
+ *
+ *      Case 2:
+ *          This page contains no key, but part of a large
+ *          data field, which is continued on the next page.
+ *
+ *          Page format it:
+ *          DATA_OFF FULL_KEY OVFL_PAGENO OVFL_PAGE
+ *
+ *          KEY_OFF -- offset of the beginning of the data on
+ *              this page
+ *          FULL_KEY -- 2
+ *          OVFL_PAGENO - page number of the next overflow page
+ *          OVFLPAGE -- 0
+ *
+ * FULL_KEY_DATA
+ *      This must be the first key/data pair on the page.
+ *      There are two cases:
+ *
+ *      Case 1:
+ *          This page contains a key and the beginning of the
+ *          data field, but the data field is continued on the
+ *          next page.
+ *
+ *          Page format is:
+ *          KEY_OFF FULL_KEY_DATA OVFL_PAGENO DATA_OFF
+ *
+ *          KEY_OFF -- offset of the beginning of the key
+ *          FULL_KEY_DATA -- 3
+ *          OVFL_PAGENO - page number of the next overflow page
+ *          DATA_OFF -- offset of the beginning of the data
+ *
+ *      Case 2:
+ *          This page contains the last page of a big data pair.
+ *          There is no key, only the  tail end of the data
+ *          on this page.
+ *
+ *          Page format is:
+ *          DATA_OFF FULL_KEY_DATA <OVFL_PAGENO> <OVFLPAGE>
+ *
+ *          DATA_OFF -- offset of the beginning of the data on
+ *              this page
+ *          FULL_KEY_DATA -- 3
+ *          OVFL_PAGENO - page number of the next overflow page
+ *          OVFLPAGE -- 0
