NAME
       Search::Dict, look - search for key in dictionary file

SYNOPSIS
           use Search::Dict;
           look *FILEHANDLE, $key, $dict, $fold;

           use Search::Dict;
           look *FILEHANDLE, $params;

DESCRIPTION
       Sets file position in FILEHANDLE to be first line greater
       than or equal (stringwise) to $key.  Returns the new file
       position, or -1 if an error occurs.

       The flags specify dictionary order and case folding:

       If $dict is true, search by dictionary order (ignore
       anything but word characters and whitespace).  The default
       is honour all characters.

       If $fold is true, ignore case.  The default is to honour
       case.

       If there are only three arguments and the third argument
       is a hash reference, the keys of that hash can have values
       "dict", "fold", and "comp" or "xfrm" (see below), and
       their correponding values will be used as the parameters.

       If a comparison subroutine (comp) is defined, it must
       return less than zero, zero, or greater than zero, if the
       first comparand is less than, equal, or greater than the
       second comparand.

       If a transformation subroutine (xfrm) is defined, its
       value is used to transform the lines read from the
       filehandle before their comparison.
