 	  With no arguments, shows available commands. First argument is
 	  name of a command to run, followed by any arguments to that command.
 
 	  --long	Show path to each command
-	  --version	Show toybox version
 
 	  To install command symlinks, try:
 	    for i in $(/bin/toybox --long); do ln -s /bin/toybox $i; done
 
+	  Most toybox commands also understand the following arguments:
+
+	  --help		Show command help (only)
+	  --version	Show toybox version (only)
+
+	  The filename "-" means stdin, "--" stops argument parsing,
+	  and numerical arguments accept a single letter suffix for
+	  kilo, mega, giga, tera, peta, and exabytes, plus an additional
+	  "d" to indicate decimal 1000's instead of 1024.
