-"SBCL is a Common Lisp programming environment. Ordinarily you shouldn't\n\
-need command line options when you invoke it interactively: you can just\n\
-start it and work with the customary Lisp READ-EVAL-PRINT loop.\n\
+"Usage: sbcl [runtime-options] [toplevel-options] [user-options]\n\
+Common runtime options:\n\
+ --help Print this message and exit.\n\
+ --version Print version information and exit.\n\
+ --core <filename> Use the specified core file instead of the default.\n\
+ --dynamic-space-size <MiB> Size of reserved dynamic space in megabytes.\n\
\n\
-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\
+Common toplevel options:\n\
+ --sysinit <filename> System-wide init-file to use instead of default.\n\
+ --userinit <filename> Per-user init-file to use instead of default.\n\
+ --no-sysinit Inhibit processing of any system-wide init-file.\n\
+ --no-userinit Inhibit processing of any per-user init-file.\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\
+User options are not processed by SBCL. All runtime options must\n\
+appear before toplevel options, and all toplevel options must\n\
+appear before user options.\n\
\n\
-More information on SBCL can be found on its man page, or at\n\
-<http://sbcl.sf.net/>.\n");
+For more information please refer to the SBCL User Manual, which\n\
+should be installed along with SBCL, and is also available from the\n\
+website <http://www.sbcl.org/>.\n");
