<P>The <CODE>read_from_{file|string}</CODE> methods and the <A HREF="../../../../lib/Pod/perlfunc.html#item_print"><CODE>print</CODE></A> method are not
isomorphic. Given an arbitrary file or string which is read in, the
output of <A HREF="../../../../lib/Pod/perlfunc.html#item_print"><CODE>print</CODE></A> is not guaranteed to be an exact duplicate of the
original file. In the special case of files that are generated with
this module, the results will be isomorphic, assuming no modifications
were made to the data between when it was read in and subsequently
written back out.</P>
<P>Since Net::Bind::Resolv does not impose many requirements on the values
of the various directives present in a <CODE>/etc/resolv.conf</CODE> file, it is
important to apply the appropriate policy methods against the object
before writing it to a file that will be used by the resolver.
Consider yourself warned!</P>
