# NAME

String::ProperCase::Surname - Converts Surnames to Proper Case

# SYNOPSIS

    use String::ProperCase::Surname;
    print ProperCase($surname);

# DESCRIPTION

The package String::ProperCase::Surname is an [Exporter](https://metacpan.org/pod/Exporter) that exports exactly one function called ProperCase.  The ProperCase function is for use on Surnames which handles cases like O'Neal, O'Brien, McLean, etc.

After researching the proper case issues there are three different use cases with a wide variety of loose rules.  This algorithm is customized for surnames.  Other uses such as "TitleCase" and "MenuCase" have different algorithms.  The main difference is that in surnames the letter following an apostrophe is always uppercase (e.g. "O'Brien") in title case and menu case the letter is always lowercase (e.g. "They're").

# USAGE

    print ProperCase($surname);
