French President Francois Hollande said he's going to do everything that he can to keep Greece in the euro.
Arriving for an emergency summit of eurozone leaders in Brussels, Hollande said "France is going to do everything to reach an agreement tonight."
He said it wasn't just Greece's future that's at stake.
"It is Europe that is at stake," he said.
Hollande also sought to douse any talk that a temporary Greek exit from the eurozone is possible. Greece is either in or out, he said.
The latter would be a retreat for Europe, said Hollande.
