Pongo is universal. The Sys file is universal.
It mean - all these lines are designed to make the user less troublesome.
You should leave a line that is intended for the version being used, and remove the character in front ( ; ).
That line becomes active. Character ; in front makes this line only treated as a comment.
Other lines are not necessary and can be delete.
So,...yes. First line is ok. Other are superfluous.
