Animating an object group

hi everyone, i’m not sure what to do, and i’m not sure how to phrase my search so i get information about my question. please move this thread if need be.

i have a multi-part object i modeled and imported into Blender (it’s got several ‘pieces’) how do i animate the entire thing so it animates as one object? thanks in advance.

For Blender 2.41, you can either join all of the pieces into a single object or parent them to a single object (or empty) and move that around.

Blender 2.42 will have groups in the traditional sense (as far as I can tell).
