SQL::Translator (also known as SQL Fairy) is a collection of Perl modules
 for manipulating structured data definitions (mostly database schemas). It
 can perform tasks like converting between different SQL data definition
 language (DDL) dialects, visualizations of schemas (pseudo-ER diagrams
 created with GD or GraphViz), converting non-RDBMS files to SQL schemas
 (xSV text files, Excel spreadsheets), serializing parsed schemas (via
 Storable, YAML and XML), creating documentation, and more.
