The HEAD block is required for all WarpIN scripts. See the "Installation Scripts" page for an overview where this tag should be placed.

Within the <HEAD> ... </HEAD>tags, you need to specify the different packages which WarpIN will be able to install for this script, using the <PCK> ... </PCK> tags.

Alternatively, if a certain archive does not contain any packages which should be installed from this archive, but are only referenced externally by another archive's install script, you can specify a warning message using the <MSG> ... </MSG> tags.

The opening <HEAD> tag has no attributes.
