I'm thinking of the build order - a list of things built, and the supply at which they were built - like the one in the comment at http://www.youtube.com/watch?v=WQe6UqvCOT4

Something like http://code.google.com/p/phpsc2replay/ will get the actions out of the replay, but I'm not sure how far along that particular library is when it comes to turning the actions into the list of stuff that was actually built (while discarding pointless spamming of hotkeys)
