+A subset of the ALTER TABLE syntax that allows addition of foreign keys:
+
+ ALTER [IGNORE] TABLE tbl_name alter_specification [, alter_specification] ...
+
+ alter_specification:
+ ADD [CONSTRAINT [symbol]]
+ FOREIGN KEY [index_name] (index_col_name,...)
+ [reference_definition]
+
+A subset of INSERT that we ignore:
+
+ 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>
