title: How to build boost required modules only?
body: <p>I just started compiling boost C++ libraries. With the following commands I issued it is building whole of the boost libraries, which is time consuming, and is not necessary for my need. </p>
  
  <p>Just unpacked the <code>boost_1_49_0.7z</code> archive and from <code>Visual Studio 2010 command line tool</code> I ran <code>bootstrap.bat</code> and it created the <code>b2</code> executable. </p>
  
  <p>Using this executable I ran <code>b2 --toolset=msvc-10.0 --build-type=complete architecture=x86 address-model=64 stage</code> to build the libraries.</p>
  
  <p>At this moment all I need is the "signals" module to be built. </p>
  
  <p>What switch commands need to be supplied to the bootstrap created executable to compile and build only those specific libraries?</p>
