In Emacs, how can I see which slime version is being used?

I just upgraded my slime using elpa in Emacs. But I wonder if 开发者_运维技巧things are like they should be now, because when I removed the old version using elpa, it complained it could not remove a certain folder. So, when I start up Emacs (I know, I shouldn't have closed it), how I can see which slime version actually gets used? Is there a command like M-x slime-version ?

When you start a REPL with the M-x slime command, the SLIME version is shown on the first line of the REPL, like:

; SLIME 20100404

Btw you can always go to your elpa folder(the one in which elpa installs the packages) and remove the problematic folder by hand.

There are no slime releases, just CVS snapshot. Use

(slime-changelog-date)

to get the latest changelog/commit date.
