=head1 NAME
Test::TempDir::Factory - A factory for creating L<Test::TempDir::Handle> objects
=head1 VERSION
version 0.10
=head1 SYNOPSIS
my $f = Test::TempDir::Factory->new;
my $d = $f->create;
$d->empty;
# ...
$d->cleanup
=head1 DESCRIPTION
This class creates L<Test::TempDir::Handle> objects with the right C<dir>
parameter, taking care of obtaining locks, creating directories, and handling
fallback logic.
=head1 ATTRIBUTES
=head2 C<lock>
Whether or not to enable locking.
Defaults to true.
=head2 C<lock_opts>
A hash reference to pass to L<File::NFSLock>.
Defaults to C<NONBLOCKING>
=head2 C<lock_attempts>
How many times to try to create and lock a directory.
Defaults to 2.
=head2 C<dir_name>
The directory under C<t_dir> to use.
Defaults to C<tmp>
=head2 C<t_dir>
Defaults to C<t>
=head2 C<use_subdir>
Whether to always use a temporary subdirectory under the temporary root.
This means that with a C<success> cleanup policy all failures are retained.
When disabled, C<t/tmp> will be used directly as C<temp_root>.
Defaults to true.
=head2 C<subdir_template>
The template to pass to C<tempdir>. Defaults to C<File::Temp::TEMPXXX>.
=head2 C<handle_class>
Defaults to L<Test::TempDir::Handle>.
=head2 C<verbose>
Whether or not to C<carp> diagnostics when falling back.
If you subclass this factory and add a C<logger> method a la L<MooseX::Logger>
then this parameter is ignored and all messages will be C<warn>ed on the
logger.
=head1 METHODS
=head2 C<create>
Create a L<Test::TempDir::Handle> object with a proper C<dir> attribute.
