[Boost-users] Iostreams and Tarballs?

Hello list, I am wanting to manage a file format used by another application in my own application. They have a tar.gz file, renamed to something else. In it, there is an XML file and some .wav sound files. Can I use Boost to handle this? I would want to parse the XML from the archive, and then load a few of the sound files. What I don't want to do is something cheesy like call the tar program from mine! That's'orrible :) Cheers for any help, and code (pseudo or otherwise) would be great. Or just a yes or no you can/can't do that would be a start. Cheers all, Gaz
