=head1 DESCRIPTION
-This is a utility that creates common L<Moose> subtypes, coercions and
-option specifications useful for dealing with L<Path::Class> objects
-as L<Moose> attributes.
+MooseX::Types::Path::Class creates common L<Moose> types,
+coercions and option specifications useful for dealing
+with L<Path::Class> objects as L<Moose> attributes.
-This module constructs coercions (see L<Moose::Util::TypeConstraints>)
+Coercions (see L<Moose::Util::TypeConstraints>) are made
from both 'Str' and 'ArrayRef' to both L<Path::Class::Dir> and
-L<Path::Class::File> objects. It also adds the Getopt option type
-("=s") for both L<Path::Class::Dir> and L<Path::Class::File>
-(see L<MooseX::Getopt>).
+L<Path::Class::File> objects. If you have L<MooseX::Getopt> installed,
+the Getopt option type ("=s") will be added for both
+L<Path::Class::Dir> and L<Path::Class::File>.
This is just meant to be a central place for these constructs, so you
-don't have to worry about whether they've been created or not, and you're
-not tempted to copy them into yet another class (like I was).

+you're not tempted to copy them into yet another class (like I was).
=head1 EXPORTS
-See L<MooseX::Types> for how these exports work.
+None of these are exported by default. They are provided via
+L<MooseX::Types>.
=over
-=item Dir is_Dir to_Dir
+=item Dir, File
+
+These exports can be used instead of the full class names. Example:
+
+ package MyClass;
+ use Moose;
+ use MooseX::Types::Path::Class qw(Dir File);
+
+ has 'dir' => (
+ is => 'ro',
+ isa => Dir,
+ required => 1,
+ coerce => 1,
+ );
+
+ has 'file' => (
+ is => 'ro',
+ isa => File,
+ required => 1,
+ coerce => 1,
+ );
+
+Note that there are no quotes around Dir or File.
+
+=item is_Dir($value), is_File($value)
+
+Returns true or false based on whether $value is a valid Dir or File.
+
+=item to_Dir($value), to_File($value)
-=item File is_File to_File
+Attempts to coerce $value to a Dir or File. Returns the coerced value
+or falue if the coercion failed.
