variants. On Windows, these are static multithreaded libraries in debug and release modes, using shared runtime. On Linux, these are static and shared multithreaded libraries in release mode.
-- complete -- Build all possible variations.
Build in this location instead of building within the distribution tree. Recommended!
Display the list of Boost libraries that require build and installation steps, and then exit.
Determine whether to choose library names and header locations such that multiple versions of Boost or multiple compilers can be used on the same system.

encoded build properties such as variant and threading, but do not including compiler name and version, or Boost version. This option is useful if you build several variants of Boost, using the same compiler.
