Macro Unknown

[Cran0g]

Hi Folks,

I'm trying to set the header text of one of the pages. I'm using:

!insertmacro MUI_LICENSEPAGE_TEXT_TOP text

But, when compiling, NSIS throws a fatal error saying that no such macro exists. I know that the details on the help page is not exactly accurate, but does anyone know how this macro should be written?

Many thanks.
