+echo Control the version of the .Net framework that is used. The
+echo command has several forms:
+echo.
+echo CLR
+echo   Reports the version of the CLR that has been set
+echo.
+echo CLR version
+echo   Sets the local shell environment to use a specific
+echo   version of the CLR for subsequent commands.
+echo.
+echo CLR version command [arguments]
+echo   Executes a single command using the specified CLR version.
+echo.
+echo CLR off
+echo   Turns off specific version selection for commands
+echo.
+echo The CLR version may be specified as vn.n.n or n.n.n. In addition,
+echo the following shortcuts are recognized:
+echo   net-1.0, 1.0           For version 1.0.3705
+echo   net-1.1, 1.1           For version 1.1.4322
+echo   beta2                  For version 2.0.50215
+echo   net-2.0, 2.0           For version 2.0.50727
+echo.
+echo NOTE:
+echo   Any specific settings for required or supported runtime in 
+echo   the ^<startup^> section of a program's config file will 
+echo   override the version specified by this command, and the
+echo   command will have no effect.
