Library to read/write TAR files

< ^ > P N |<>| ^ _>< --- | ~ ...Help

Hello,

I'm looking for a library to read/write TAR files. I've had a look on  
RubyForge and searched for one on Google but found nothing (except an  
old library that doesn't seem to be maintained anymore). Does anyone  
know such a library?

Thanks
