	 use Sys::MemInfo qw(totalmem freemem totalswap);

	 print "total memory: ".(&totalmem / 1024)."
";
	 print "free memory:  ".(&freemem / 1024)."
";

	 print "total swap: ".(&totalswap / 1024)."
";
	 print "free swap:  ".(Sys::MemInfo::get("freeswap") / 1024)."
";

       availkeys
	   Return list of all accessor keys (freemem, totalmem, etc.)  This is useful for dumping out all known information from the object by
	   calling get() on all of the returned keys.

       freemem
	   Returns free physical memory in bytes.

       freeswap
