title: Boost.Asio as header-only
body: <p>I want to use ASIO library from Boost in my project. Its doc say it can be header-only if regex is not used and SSL not used. However, running <code>bcp</code> for <code>asio</code> pulls a very many libraies some of which are with sources so need compiling, <code>bjam</code> etc.</p>
  
  <p>Can I somehow use ASIO in project as only headers, without libs/source? I only need ASIO, not other part of Boost.</p>
  
  <p>EDIT: ASIO want <code>Boost.System</code> which has a lib to link - can this dependency not be so that I can use header only ASIO?</p>
