+
+SQL::Translator::Producer::MySQL - MySQL-specific producer for SQL::Translator
+
+=head1 SYNOPSIS
+
+Use via SQL::Translator:
+
+ use SQL::Translator;
+
+ my $t = SQL::Translator->new( parser => '...', producer => 'MySQL', '...' );
+ $t->translate;
+
+=head1 DESCRIPTION
+
+This module will produce text output of the schema suitable for MySQL.
+There are still some issues to be worked out with syntax differences
+between MySQL versions 3 and 4 ("SET foreign_key_checks," character sets
+for fields, etc.).
