=head1 NAME
File::HomeDir::Darwin - Find your home and other directories on Darwin (OS X)
=head1 DESCRIPTION
This module provides Darwin-specific implementations for determining
common user directories. In normal usage this module will always be
used via L<File::HomeDir>.
Note -- since this module requires Mac::Carbon and Mac::Carbon does
not work with 64-bit perls, on such systems, File::HomeDir will try
L<File::HomeDir::Darwin::Cocoa> and then fall back to the (pure Perl)
L<File::HomeDir::Darwin>.
=head1 SYNOPSIS
use File::HomeDir;
# Find directories for the current user
$home = File::HomeDir->my_home; # /Users/mylogin
$desktop = File::HomeDir->my_desktop; # /Users/mylogin/Desktop
$docs = File::HomeDir->my_documents; # /Users/mylogin/Documents
$music = File::HomeDir->my_music; # /Users/mylogin/Music
$pics = File::HomeDir->my_pictures; # /Users/mylogin/Pictures
$videos = File::HomeDir->my_videos; # /Users/mylogin/Movies
$data = File::HomeDir->my_data; # /Users/mylogin/Library/Application Support
