From yesterday:

"The US Federal Reserve authorized the introduction of 180 billion dollars in cash on the financial markets, within a common move of the world's central banks, Fed Reserve informs in a press release on Thursday. Fed also announced signing swap lines agreements with the European Central Bank, the Bank of England, the Bank of Japan and the Canadian Central Bank. "

So who gets that money, for how long, against what interest rate, and against what collateral? Second what do swap lines between central banks establish?
