+One option idiom which is sometimes useful interactively (e.g. when\n\
+exercising a test case for a bug report) is\n\
+ sbcl --sysinit /dev/null --userinit /dev/null\n\
+to keep SBCL from reading any initialization files at startup. And some\n\
+people like to suppress the default startup message:\n\
+ sbcl --noinform\n\
+\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\
+information on such options, see the sbcl(1) man page.\n\
