=head1 NAME

HTTP::Thin - A Thin Wrapper around HTTP::Tiny to play nice with HTTP::Message

=head1 VERSION

version 0.006

=head1 SYNOPSIS

    use 5.12.1;
    use HTTP::Request::Common;
    use HTTP::Thin;

    say HTTP::Thin->new()->request(GET 'http://example.com')->as_string;

=head1 DESCRIPTION

WARNING: This module is untested beyond the very basics. The implementation is simple enough that it shouldn't do evil things but, yeah it's still not approved for use by small children.

C<HTTP::Thin> is a thin wrapper around L<HTTP::Tiny> adding the ability to pass in L<HTTP::Request> objects and get back L<HTTP::Response> objects. The maintainers of L<HTTP::Tiny>, justifiably, don't want to have to maintain compatibility but many other projects already consume the L<HTTP::Message> objects. This is just glue code doing what it does best.

=head1 METHODS

=head2 request

In addition to the parameters documented in L<HTTP::Tiny>, C<HTTP::Thin> takes L<HTTP::Request> objects as well. 

The return value is an L<HTTP::Response> object.

=head1 WHY?

A conversation on IRC lead to C<mst>, C<ether>, and I agreeing that this would be a useful module but probably not worth the effort. I wrote it anyway to get it out of my head.
