FASTHELP--Note

You can use FASTHELP to get online Help for a command in two ways. You can  
specify the name of the command on the FASTHELP command line, or you can
type the name of the command and the /? switch at the command prompt. For
example, you can type either of the following commands to get information
about the XCOPY command:

    fasthelp xcopy

    xcopy /?

The second command is slightly faster.
