  47 <p>Sets file position in FILEHANDLE to be first line greater than or equal
  48 (stringwise) to <em>$key</em>.  Returns the new file position, or -1 if an error
  49 occurs.</p>
  50 <p>The flags specify dictionary order and case folding:</p>
  51 <p>If <em>$dict</em> is true, search by dictionary order (ignore anything but word
  52 characters and whitespace).  The default is honour all characters.</p>
  53 <p>If <em>$fold</em> is true, ignore case.  The default is to honour case.</p>
  54 <p>If there are only three arguments and the third argument is a hash
  55 reference, the keys of that hash can have values <code>dict</code>, <code>fold</code>, and
  56 <code>comp</code> or <code>xfrm</code> (see below), and their correponding values will be
  57 used as the parameters.</p>
  58 <p>If a comparison subroutine (comp) is defined, it must return less than zero,
  59 zero, or greater than zero, if the first comparand is less than,
  60 equal, or greater than the second comparand.</p>
  61 <p>If a transformation subroutine (xfrm) is defined, its value is used to
  62 transform the lines read from the filehandle before their comparison.</p>
