=head1 NAME

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

=head1 SYNOPSIS

    use Text::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.

    # "Faster" version for working with scalars only; complementing lc and uc.

    use Text::NameCase qw( nc ) ;

    $FixedCasedName  = nc( $OriginalName ) ;

    $FixedCasedName  = nc( \$OriginalName ) ;

=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, space separated, NameCase and nc deal
correctly with them.

NameCase currently correctly name cases names which include any of the
following:
    Mc, Mac, el, ap, da, de, di, du, del, der, la, le, 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.

=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.

We don't fix "ben" - for hebrew names this means son of, but it can
mean "Ben" as a name in itself or as a form of "Benjamin". Similarly we
don't fix "al" - for arabic names this means son of, but it can also
mean "Al" as a name in itself.

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