=head1 NAME

Plack::LWPish - HTTP::Request/Response compatible interface with HTTP::Tiny backend

=head1 SYNOPSIS

  use Plack::LWPish;

  my $request = HTTP::Request->new(GET => 'http://perl.com/');

  my $ua = Plack::LWPish->new;
  my $res = $ua->request($request); # returns HTTP::Response

=head1 DESCRIPTION

This module is an adapter object that implements one method,
C<request> that acts like L<LWP::UserAgent>'s request method
i.e. takes HTTP::Request object and returns HTTP::Response object.

This module is used solely inside L<Plack::Test::Suite> and
L<Plack::Test::Server>, and you are recommended to take a look at
L<HTTP::Thin> if you would like to use this outside Plack.
