-
-This option uses L<Getopt::Long>'s ability to specify a hash 
-structure with command line options.  Basically, for every 
-clause that you want to include in the WHERE statement you 
-have a --where option specifying the clause.  So, if you wanted 
-to specify two clauses you would do:
-
-  --where this=that --where those=these
-
-And that will become something like:
-
-  WHERE this="that" AND those="these"
-
-The insert does not suppor the where option and will croak if 
-you try to use it.
-
-=head2 set
-
-This works just like the where option except that the insert 
-operation does support it, but the delete operation does not.
