echo Usage: %0 [/?] [^<options^>] [--] [^<cl-compiler^>] [^<compile-options^>] [-- ^<link-options^>]
echo Options:
echo   --local                Don't build from packages, only from local source.
echo   --no-bpkg              Don't install bpkg nor bdep ^(requires --local^).
echo   --no-bdep              Don't install bdep.
echo   --no-modules           Don't install standard build system modules.
echo   --modules "<list>"     Install only specified standard build system modules.
echo   --install-dir ^<dir^>    Alternative installation directory.
echo   --exe-prefix ^<pfx^>     Toolchain executables name prefix.
echo   --exe-suffix ^<sfx^>     Toolchain executables name suffix.
echo   --stage-suffix ^<sfx^>   Staged executables name suffix ^('-stage' by default^).
echo   --jobs^|-j ^<num^>        Number of jobs to perform in parallel.
echo   --repo ^<loc^>           Alternative package repository location.
echo   --trust ^<fp^>           Repository certificate fingerprint to trust.
echo   --timeout ^<sec^>        Network operations timeout in seconds.
echo   --verbose ^<level^>      Diagnostics verbosity level between 0 and 6.
echo.
echo By default the batch file will use cl.exe as the C++ compiler and install
echo into C:\build2. It also expects to find the base utilities in the bin\
echo subdirectory of the installation directory ^(C:\build2\bin\ by default^).
echo.
echo If --jobs^|-j is unspecified, then the number of available hardware
echo threads is used.
echo.
echo The --trust option recognizes two special values: 'yes' ^(trust everything^)
echo and 'no' ^(trust nothing^).
echo.
echo The script by default installs the following standard build system
echo modules:
echo.
echo %standard_modules%
echo.
echo Use --no-modules to suppress installing build system modules or
echo --modules "<list>" to specify a comma-separated subset to install.
echo.
echo See the BOOTSTRAP-WINDOWS-MSVC file for details.
