HELP

Command-line help for console commands.

Most commands will give help when run with:

COMMAND /?
or
COMMAND -?

Help will not detect if Command Extensions have disabled and will print help messages assuming the extensions are available.

GUI Help files (WINHELP and WINHLP32.exe) are no longer supported.
