MetaL meta-programming language

MetaL is a meta-programming language that works by generating source code in a target language from a program specification in a higher level language. MetaL programs are based on XML. The compiler engine generates programs in potentially any target language - PHP, Java, and Perl are currently supported.

            Release Notes: This release introduces the first meta-meta-programming MetaL compiler module - a data persistence layer module that generates classes of objects from XML descriptions of object properties and relationships between the objects of different classes. It also generates schemas in a database independent XML format that can be used with many types of databases where object data is stored persistently.
