DBIx::Schema now on SourceForge
An obscure but somewhat useful little Perl module for Lazy database use that I wrote for a workplace application (and made open source through the good graces of Adelphia Business Solutions), DBIx::Schema now lives on SourceForge. Yay.

DBIx-Schema 0.07 file released: DBIx-Schema-0.07.tar.gz
New in version 0.07 (the latest, as of July 15, 2000): The module used to choke on databases containing circular relationship paths; i.e., allowing two or more different ways to relate tables A and B. It now picks the shortest available path (or picks one of the shortest and generates a warning if there is a tie). These additional checks make its schema-crawling a tad slower, adding about a thousandth of a second of CPU time to a simple statement handle construction, according to the Benchmark module on my P-266, and more time if it has lots of circular paths to walk to choose from (at which point I question your database design philosophy anyway ;-) ), but I consider this a reasonable cost for fixing this yucky bug. New in version 0.06: The interface was pathological in some places, and so has been simplified. The statement handle constructor now takes a 'table' key, rather than 'fields', which was rather misleading. The previous version of this module leaked memory like nobody's business when used in a sustained environment (such as with mod_perl), due to a big ol' circular reference. This has been quashed. The documentation was similarly schizophrenic here and there, and has also seen corrections and clarifications. The test scripts actually work now, on at least one machine. Andy Turner (of DBIx::Abstract fame) got his fingers into it, writing the Datadict module, which speeds up DBIx::Schema quite a bit. It is included with this distribution.
