=head1 NAME
Mojo - Duct tape for the HTML5 web!
=head1 SYNOPSIS
  use Mojo::Base 'Mojo';
  # All the complexities of CGI, PSGI, HTTP and WebSockets get reduced to a
  # single method call!
  sub handler {
    my ($self, $tx) = @_;
    # Request
    my $method = $tx->req->method;
    my $path   = $tx->req->url->path;
    # Response
    $tx->res->code(200);
    $tx->res->headers->content_type('text/plain');
    $tx->res->body("$method request for $path!");
    # Resume transaction
    $tx->resume;
  }
=head1 DESCRIPTION
Mojo provides a flexible runtime environment for Perl real-time web
frameworks.
It provides all the basic tools and helpers needed to write simple web
applications and higher level web frameworks such as L<Mojolicious>.
See L<Mojolicious> for more!
=head1 ATTRIBUTES
L<Mojo> implements the following attributes.
=head2 C<home>
  my $home = $app->home;
  $app     = $app->home(Mojo::Home->new);
The home directory of your application, defaults to a L<Mojo::Home> object
which stringifies to the actual path.
  my $path = $app->home->rel_file('data/important.txt');
=head2 C<log>
  my $log = $app->log;
  $app    = $app->log(Mojo::Log->new);
The logging layer of your application, defaults to a L<Mojo::Log> object.
  $app->log->debug('It works!');
=head2 C<ua>
  my $ua = $app->ua;
  $app   = $app->ua(Mojo::UserAgent->new);
A full featured HTTP 1.1 user agent for use in your applications, defaults to
a L<Mojo::UserAgent> object.
=head1 METHODS
L<Mojo> inherits all methods from L<Mojo::Base> and implements the following
new ones.
=head2 C<new>
  my $app = Mojo->new;
Construct a new L<Mojo> application.
Will automatically detect your home directory and set up logging to
C<log/mojo.log> if there's a C<log> directory.
=head2 C<build_tx>
  my $tx = $app->build_tx;
Transaction builder, defaults to building a L<Mojo::Transaction::HTTP>
object.
=head2 C<handler>
  $tx = $app->handler($tx);
The handler is the main entry point to your application or framework and
will be called for each new transaction, which will usually be a
L<Mojo::Transaction::HTTP> or L<Mojo::Transaction::WebSocket> object.
  sub handler {
    my ($self, $tx) = @_;
  }
