         -t|--trace   Turn on tracing for Parse::RecDescent
         -c|--case-insensitive   Compare tables/columns case-insensitively
         --ignore-index-names    Ignore index name differences
         --ignore-constraint-names   Ignore constraint name differences
         --mysql_parser_version=<#####> Specify a target MySQL parser version

         --output-db=<Producer>  This Producer will be used instead of one
                                 corresponding to parser1 to format output
                                 for new tables
         --ignore-view-sql    Ignore view SQL differences
         --ignore-proc-sql    Ignore procedure SQL differences
         --no-batch-alters    Do not clump multile alters to the same table into a

DESCRIPTION
       sqlt-diff is a utility for creating a file of SQL commands necessary to
       transform the first schema provided to the second.  While not yet
       exhaustive in its ability to mutate the entire schema, it will report
       the following

       o   New tables

           Using the Producer class of the target (second) schema, any tables
           missing in the first schema will be generated in their entirety
           (fields, constraints, indices).

       o   Missing/altered fields

           Any fields missing or altered between the two schemas will be
           reported as:

             ALTER TABLE <table_name>
               [DROP <field_name>]
               [CHANGE <field_name> <datatype> (<size>)] ;

       o   Missing/altered indices

       ALTER, CREATE, DROP statements are created by
       SQL::Translator::Producer::*, see there for support/problems.

       Currently (v0.0900), only MySQL is supported by this code.
