treelang-3.4 3.4.3-9ubuntu4 (amd64 binary) in ubuntu hoary

The GNU Treelang compiler
 Treelang is a sample language, useful only to help people understand how
 to implement a new language front end to GCC. It is not a useful
 language in itself other than as an example or basis for building a new
 language. Therefore only language developers are likely to have an
 interest in it.
