Er.... it wouldn't do that without first telling you what you were going to 
remove and giving you a chance to say NO.  (and btw, purging libreadline5-
dev _wouldn't_ remove libreadline5, they're different - and you wouldn't 
normally need the -dev package).

Purge and remove are essentially the same, except that remove leaves config 
files behind.  You'll never even notice what clean does - it just cleans out 
the archive of already installed packages.
