=head1 NAME

NameCase - Perl module to fix the case of people's names.

=head1 SYNOPSIS

    # Working with scalars; complementing lc and uc.

    use Lingua::EN::NameCase qw( nc ) ;

    $FixedCasedName  = nc( $OriginalName ) ;

    $FixedCasedName  = nc( \$OriginalName ) ;

    # Working with arrays or array references.

    use Lingua::EN::NameCase 'NameCase' ;

    $FixedCasedName  = NameCase( $OriginalName ) ;
    @FixedCasedNames = NameCase( @OriginalNames ) ;

    $FixedCasedName  = NameCase( \$OriginalName ) ;
    @FixedCasedNames = NameCase( \@OriginalNames ) ;

    NameCase( \@OriginalNames ) ; # In-place.

    # NameCase will not change a scalar in-place, i.e.
    NameCase( \$OriginalName ) ; # WRONG: null operation.

    $Lingua::EN::NameCase::SPANISH = 1;
    # Now 'El' => 'El' instead of (default) Greek 'El' => 'el'.
    # Now 'La' => 'La' instead of (default) French 'La' => 'la'.

=head1 DESCRIPTION

Forenames and surnames are often stored either wholly in UPPERCASE
or wholly in lowercase. This module allows you to convert names into
the correct case where possible.

Although forenames and surnames are normally stored separately if they
do appear in a single string, whitespace separated, NameCase and nc deal
correctly with them.

NameCase currently correctly name cases names which include any of the
following:
    Mc, Mac, al, el, ap, da, de, delle, della, di, du, del, der, 
    la, le, lo, van and von.

It correctly deals with names which contain apostrophies and hyphens too.

=head2 EXAMPLE FIXES

    Original            Name Case
    --------            ---------
    KEITH               Keith
    LEIGH-WILLIAMS      Leigh-Williams
    MCCARTHY            McCarthy
    O'CALLAGHAN         O'Callaghan
    ST. JOHN            St. John

plus "son (daughter) of" etc. in various languages, e.g.:

    VON STREIT          von Streit
    VAN DYKE            van Dyke
    AP LLWYD DAFYDD     ap Llwyd Dafydd
etc.

plus names with roman numerals (up to 89, LXXXIX), e.g.:

    henry viii          Henry VIII
    louis xiv           Louis XIV

=head1 BUGS

The module covers the rules that I know of. There are probably a lot
more rules, exceptions etc. for "Western"-style languages which could be
incorporated.

There are probably lots of exceptions and problems - but as a general
data 'cleaner' it may be all you need.

Use Kim Ryan's NameParse.pm for any really sophisticated name parsing.

=head1 CHANGES

These are the original change comments. These have now been moved to the new
Changes file within the distribution.

1998/04/20  First release.

1998/06/25  First public release.

1999/01/18  Second public release.

1999/02/08  Added Mac with Mack as an exception, thanks to Kim Ryan for this.

1999/05/05  Copied Kim Ryan's Mc/Mac solution from his NameParse.pm and 
            replaced my Mc/Mac solution with his.

1999/05/08  nc can now use $_ as its default argument 
            e.g. "$ans = nc ;" and "nc ;", both of which set $_, with the
            first one setting $ans also.

1999/07/30  Modified for CPAN and automatic testing. Stopped using $_ as the
            default argument.

1999/08/08  Changed licence to LGPL.

1999/09/07  Minor change to packaging for CPAN.

1999/09/09  Renamed package Lingua::EN::NameCase.pm as per John Porter's
            (CPAN) suggestion.

1999/11/13  Added code for names with roman numerals, thanks to David Lynn
            Rice for this suggestion. (If you need to go beyond LXXXIX let me
            know.)

2000/11/22  Added use locale at the suggestion of Eric Kolve. It should have
    	    been there in the first place.

2002/04/25  Al, Ben and Van are preserved if single names and namecased 
	        otherwise, e.g. 'Al' => 'Al', 'Al Fahd' => 'al Fahd'. Added
	        $SPANISH_EL variable. All thanks to a suggestion by Aaron
    	    Patterson.

2002/04/26  Changed $SPANISH_EL to $SPANISH and now 'La' => 'la' unless 
	        $SPANISH is set in which case 'La' => 'La'. Again thanks to
	        Aaron Patterson.

2007/04/27  Added 16 "Mac" exceptions provided by Stuart McConnachie.
    	    The license is now "the same terms as Perl itself".

2008/02/07  Fixed the version number.
