To download SLIME you first configure your CVSROOT and login
to the repository.
export CVSROOT=:pserver:anonymous@common-lisp.net:/project/slime/cvsroot
cvs login
(The password is anonymous)
The latest version can then be checked out with:
cvs checkout slime
Or the FAIRLY-STABLE version can be checked out with:
cvs checkout -rFAIRLY-STABLE slime
If you want to find out what's new since the version you're currently running, you can diff the local ChangeLog against the repository version:
cvs diff -rHEAD ChangeLog # or: -rFAIRLY-STABLE
