Constructor. Creates a new SelectSaver object,
$saver, which saves the
current filehandle. The optional parameter
fh is the filehandle that will temporarily
replace the current filehandle. If fh is
present, the current filehandle is saved in
$saver, and the new one
becomes the current filehandle. With no parameter, the current
filehandle is saved in the object
$saver, and it remains
current.

You can use the newly selected filehandle within the current block.
When you exit the block, the previous filehandle is again made the
current one, and the SelectSaver object in which it was stored is
destroyed.
