SQL::Translator::Parser::MySQL - parser for MySQL
table_options:
TYPE = {BDB | HEAP | ISAM | InnoDB | MERGE | MRG_MYISAM | MYISAM }
+ or ENGINE = {BDB | HEAP | ISAM | InnoDB | MERGE | MRG_MYISAM | MYISAM }

or DATA DIRECTORY="absolute path to directory"
or INDEX DIRECTORY="absolute path to directory"
+
A subset of the ALTER TABLE syntax that allows addition of foreign keys:
ALTER [IGNORE] TABLE tbl_name alter_specification [, alter_specification] ...
INSERT anything
+=head1 ARGUMENTS
+
+This parser takes a single optional parser_arg C<mysql_parser_version>, which
+provides the desired version for the target database. Any statement in the processed
+dump file, that is commented with a version higher than the one supplied, will be stripped.
+
+Valid version specifiers for C<mysql_parser_version> are listed L<here|SQL::Translator::Utils/parse_mysql_version>
+
+More information about the MySQL comment-syntax: L<http://dev.mysql.com/doc/refman/5.0/en/comments.html>
