What happens to retired Popes like Pope Benedict? Does the pope get paid for being the pope?

The above question is answered very well and shows that the Pope genuinely has no personal assets. He is well cared for by the Vatican. 

But what about the recently resigned Pope Benedict. He is no longer Pope and likely has very little or even no personal assets. What will happen to him?

This is interesting to know because I think only two or three Popes have actually ever resigned. Most die in office. So there is no Papal retirement fund and I would think not really any official or traditional way of handling this.
While it's not one of our usual sources for Christian views, CNN did an article discussing this, and given that this is the first retired Pope in 600 years, and the occurrence is extremely rare, their answer is actually pretty good...

His needs will still be seen to.  There is no dictate as to what he should do, per Catholic doctrine, but he has indicated what he intends to do.

First, the statement that his needs will be seen to are addressed here:


  The 85-year-old will first leave Rome to go to the papal seaside
  retreat, Castle Gandolfo, until a successor is named. Then he will
  head to the Mater Ecclesiae (Mother of the Church) building, which
  formerly housed a cloistered convent in the Vatican gardens.


Later on, the article explores what he intends to do in this retreat - Devote his life to prayer:


  In the chapel the pope might say Mass every day for his small
  household, said Monsignor Rick Hilgartner, executive director of the
  U.S. Conference of Catholic Bishops' Secretariat of Divine Worship.
  
  Benedict has said he will devote his life to prayer. There is no
  playbook for the life of prayer for a retired pope, Hilgartner said.
  "Nothing beyond the normal routine" for a monk or a priest.
  
  He said that would include "prayer throughout the day and the liturgy
  of the hours, morning prayer, evening prayer, Mass every day."


As for his financial needs:


  There may be a stipend for the retired pope. Italian news outlets have
  reported retired clerics receive up to €2,500 a month. Hilgartner said
  Benedict won't need much money if any at all. The Vatican will take
  care of his lodging and his health care.
  
  "He didn't have a pension because the presumption was he would be in
  office until he died," Hilgartner said. "His needs will be cared for.
  Because of the way he'll be living, those needs will be somewhat
  limited."


Historically, however, for how the other Popes that have retired....


St. Pontian was martyred in 236 
Benedict IX retired to the Abbey of Grottaferrata, where he repented of his sins, officially resigned as pope and spent the rest of his life doing penance.
St. Celestine V resigned on Dec. 13, 1294, and returned to his monastery. His successor, Pope Boniface VIII, had him imprisoned so that there would be no attempt to place him on the throne again.
