:Usage
echo.%~nx0 [flags and arguments] [quoted MSBuild options]
echo.
echo.Build CPython from the command line.  Requires the appropriate
echo.version(s) of Microsoft Visual Studio to be installed (see readme.txt).
echo.
echo.After the flags recognized by this script, up to 9 arguments to be passed
echo.directly to MSBuild may be passed.  If the argument contains an '=', the
echo.entire argument must be quoted (e.g. `%~nx0 "/p:PlatformToolset=v100"`)
echo.
echo.Available flags:
echo.  -h  Display this help message
echo.  -V  Display version information for the current build
echo.  -r  Target Rebuild instead of Build
echo.  -d  Set the configuration to Debug
echo.  -e  Build external libraries fetched by get_externals.bat
echo.      Extension modules that depend on external libraries will not attempt
echo.      to build if this flag is not present
echo.  -m  Enable parallel build (enabled by default)
echo.  -M  Disable parallel build
echo.  -v  Increased output messages
echo.  -k  Attempt to kill any running Pythons before building (usually done
echo.      automatically by the pythoncore project)
echo.  --pgo          Build with Profile-Guided Optimization.  This flag
echo.                 overrides -c and -d
echo.  --test-marker  Enable the test marker within the build.
echo.
echo.Available flags to avoid building certain modules.
echo.These flags have no effect if '-e' is not given:
echo.  --no-ssl      Do not attempt to build _ssl
echo.  --no-tkinter  Do not attempt to build Tkinter
echo.
echo.Available arguments:
echo.  -c Release ^| Debug ^| PGInstrument ^| PGUpdate
echo.     Set the configuration (default: Release)
echo.  -p x64 ^| Win32
echo.     Set the platform (default: Win32)
echo.  -t Build ^| Rebuild ^| Clean ^| CleanAll
echo.     Set the target manually
echo.  --pgo-job  The job to use for PGO training; implies --pgo
echo.             (default: "-m test --pgo")
exit /b 127
