+One option idiom which is sometimes useful interactively (e.g. when\n\

+ sbcl --noinform\n\

+Other options can be useful when you're running SBCL noninteractively,\n\
+e.g. from a script, or if you have a strange system configuration, so\n\
+that SBCL can't by default find one of the files it needs. For\n\
