=head1 NAME

File::HomeDir::Darwin::Cocoa - Find your home and other directories on Darwin (OS X)

=head1 DESCRIPTION

This module provides Darwin-specific implementations for determining
common user directories using Cocoa API through
L<Mac::SystemDirectory>.  In normal usage this module will always be
used via L<File::HomeDir>.

Theoretically, this should return the same paths as both of the other
Darwin drivers.

Because this module requires L<Mac::SystemDirectory>, if the module
is not installed, L<File::HomeDir> will fall back to 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
