Hello Rubyists, I would like to announce the release of my first Ruby project: MP4Info. Please use and abuse the library and please give me any hints, tips and tricks to make a better mousetrap; I haven’t been in the Ruby game for long. Briefly, MP4Info supports the reading of tags and file info from MP4 audio files and is based on the Perl module MP4::Info ([search.cpan.org/~jhar/MP4-Info/](http://search.cpan.org/~jhar/MP4-Info/)). For more information please visit the MP4Info RubyForge site at [http://rubyforge.org/projects/mp4info/](http://rubyforge.org/projects/mp4info/) and the RDocs at [http://mp4info.rubyforge.org/](http://mp4info.rubyforge.org/) Note that Unicode tags are not correctly read; any tips on this matter would be greatly appreciated. Thanks for your time and your interest in MP4Info, -Jason Terk ---
