Prepackaged Bankruptcy

Can someone explain to me how this works? It seems like a good idea, but I don’t understand the mechanics.

President-Elect Barack Obama‘s transition team is exploring a swift, prepackaged bankruptcy for automakers as a possible solution to the industry’s financial crisis, according to a person familiar with the matter.

Obama’s team has already contacted at least one bankruptcy- law firm to say that Daniel Tarullo, a professor at Georgetown University’s law school who heads Obama’s economic policy working group, would call to discuss the workings of a so-called prepack, according to this person.
