Let the installer add the clink directory location %CLINK_DIR% to the path.

When using the installer, provide an option to add the clink directory location to the path.

Add variable %CLINK_DIR% to the path.
set path=%CLINK_DIR%;%path%

Afterwards one can open a cmd prompt and typ clink (or clink.bat) to start a new clink shell.
Handy when not using the "Autorun when cmd.exe starts" option.
