+     *                                Currently, only the sorting property is supported. It should be used
+     *                                 to define the sorting direction of the index. It may be set to either
+     *                                 ascending or descending.
+     *
+     *                                Not all DBMS support index sorting direction configuration. The DBMS
+     *                                 drivers of those that do not support it ignore this property. Use the
+     *                                 function support() to determine whether the DBMS driver can manage indexes.

+     *                                Currently, only the sorting property is supported. It should be used
+     *                                 to define the sorting direction of the index. It may be set to either
+     *                                 ascending or descending.
+     *
+     *                                Not all DBMS support index sorting direction configuration. The DBMS
+     *                                 drivers of those that do not support it ignore this property. Use the
+     *                                 function supports() to determine whether the DBMS driver can manage indexes.

+// | QuerySim was originally created for use during development of        |
+// | applications built using the Fusebox framework. (www.fusebox.org)    |
+// | Fusebox uses an XML style of documentation called Fusedoc. (Which    |
+// | is admittedly not well suited to documenting classes and functions.  |
+// | This short-coming is being addressed by the Fusebox community.) PEAR |
+// | uses a Javadoc style of documentation called PHPDoc. (www.phpdoc.de) |
+// | Since this class extension spans two groups of users, it is asked    |
+// | that the members of each respect the documentation standard of the   |
+// | other.  So it is a further requirement that both documentation       |
+// | standards be included and maintained. If assistance is required      |
+// | please contact Alan Richmond.                                        |

+                numCols, numRows, getSpecialQuery
+            David Huyck (bombusbee.com) added ability to escape special
+                characters (i.e., delimiters) using a '\'.
+            Extended PEAR DB options[] for adding incoming parameters.  Added
+                options:  columnDelim, dataDelim, eolDelim

+        <history author="David Huyck" email="b@bombusbee.com" type="Update" date="19-July-2002">
+            Added the ability to set the QuerySim options at runtime.

+                'columnDelim' => ',',            // Commas split the column names
+                'dataDelim'   => '|',            // Pipes split the data fields

+            Affected functions are:
+                DB_querysim():          set the default options when the
+                                        constructor method is called
+                _parseQuerySim($query): altered the parsing of lines, column

+                _empty2null:            altered the way this function is called
+                                        to simplify calling it

+                                    lineData.
+            Cleanup:
+                PEAR compliant formatting, finished PHPDocs and added 'out' to
+                Fusedoc 'io'.
+                Broke up _parseQuerySim() into _buildResult() and _parseOnDelim()

+            Removed protected function _empty2null().  Turns out preg_split()
+            deals with empty elemants by making them zero length strings, just

+            Affected functions:
+                _parseOnDelim()     perform trim on line here, instead of in
