   $ONELINER$

   $SYNTAX$
      ft_Metaph( <cName> [, <nSize> ] ) -> cMetaPhone
   $ARGUMENTS$
      <cName> is the character string to convert

      <nSize> is the length of the character string to be returned.
              If not specified the default length is 4 bytes.
   $RETURNS$
      A phonetically spelled character string
   $DESCRIPTION$
      This function is a character function use to index and search for
      sound-alike or phonetic matches.  It is an alternative to
      the SoundEx() function, and addresses some basic pronunciation
      rules, by looking at surrounding letters to determine how parts of
      the string are pronounced.  ft_Metaph() will group sound-alikes
      together, and forgive shortcomings in spelling ability.
   $EXAMPLES$
      USE persons
      INDEX ON ft_Metaph( LastName ) TO lastname
      SEEK ft_Metaph( "Philmore" )
      ? Found(), field->LastName       // Result: .T. Philmore
      SEEK ft_Metaph( "Fillmore" )
      ? Found(), field->LastName       // Result: .T. Philmore
   $END$
