## New Escaping

THIS IS IMPORTANT FOR EVERYONE!

The gph format has been changed, to simplify things in the future.

In the past, the escape for some line to not be interpreted was

	ttext is here

becomes

	text is here

This has changed. All lines beginning with t are now not escaped anymore.

The new escape way is:

	[|text is here

becomes

	text is here

In every gph script you already had to check for any line beginning with
'['. Now the already illegal case of an empty item type is reused for
escaping in gph.

This will make life easier for newcomers and oldcomers.

So be sure to change all escaping after the upgrade.
