+echo.
+echo Usage: %0 [/?] [^<options^>] [^<clang++-compiler^>]
+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   --install-dir ^<dir^>  Alternative installation directory.
+echo   --repo ^<loc^>         Alternative package repository location.
+echo   --trust ^<fp^>         Repository certificate fingerprint to trust.
+echo   --timeout ^<sec^>      Network operations timeout in seconds.
+echo   --make ^<arg^>         Bootstrap using GNU make instead of batch file.
+echo   --verbose ^<level^>    Diagnostics verbosity level between 0 and 6.
+echo.
+echo By default the batch file will use clang++.exe as the C++ compiler and
+echo install into C:\build2. It also expects to find the base utilities in the
+echo bin\ subdirectory of the installation directory ^(C:\build2\bin\ by
+echo default^).
+echo.
+echo The --trust option recognizes two special values: 'yes' ^(trust everything^)
+echo and 'no' (trust nothing).
+echo.
+echo The --make option can be used to bootstrap using GNU make. The first
+echo --make value should specify the make executable optionally followed by
+echo additional make options, for example:
+echo.
+echo %0 --make mingw32-make --make -j8
+echo.
+echo See the BOOTSTRAP-WINDOWS-CLANG file for details.
