Are you looking for a programatic or scripting solution? Programatically, look at Launch Services (LSCopyAllRoleHandlersForContentType() for instance). For scripting, you probably want lsregister which is buried down in
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Support
Don't let its location in the docs fool you. It in the Carbon docs, but it's actually CoreServices, which is not deprecated.
