-          lets you provide arguments to NSE-scripts. Arguments are passed as 
-		  name=value pairs. The provided argument is processed and stored
-		  inside a Lua table, to which all scripts have access. The names are
-		  taken as strings (which have to be alphanumeric values) and used as
-		  keys inside the argument-table. Values are either strings or tables
-		  themselves (starting with a '{' and ending with a '}'). Subtables make
-		  it possible to override arguments for specific scripts (e.g. when you
-		  want to provide different login/password pairs for different scripts).
-		  An argument of
-		  <literal>user=bar,password=foo,anonFTP={password=nobody@foobar.com} 
-		  </literal> for example results in the following table provided to
-		  NSE-scripts:
-		  <literal>t={user="bar",password="foo",anonFTP={password="nobody@foobar.com"}</literal>.
-		  Note, that if you want to override an option to a script, you should
-		  index the subtable with the script's <literal>id</literal>, since this
-		  is the only way the script knows about its special argument.
