Usage: bjam [OPTION]... DIR[-CPP_FILE_NAME]
Build and run Boost.Contract tests and examples.
Using Boost libraries from environment variable: $BOOST_ROOT = $(BOOST_ROOT)

Options:
  boost_contract_link=shared,        build Boost.Contract library as shared,
                      static,header  static, or header-only (shared by default)
  boost_contract_no=all_yes,         contract checking off (all_yea by default)
                    $(all_nos)

Examples (on Linux-based bash):
  Build just \"test/public_function/body_throw.cpp\":
    [test]$ bjam public_function-body_throw
  Build all targets using MSVC, GCC, and CLang compilers:
          $ time bjam -q toolset=msvc,gcc,clang ; echo $?
  Build with all linkages on multiple compilers:
          $ time bjam -q toolset=msvc,gcc,clang boost_contract_link=static,header ; echo $?
  Build with all contract checking combinations on multiple compilers:
          $ time bjam -q toolset=msvc,gcc,clang boost_contract_no=$(all_nos) ; echo $?
