Citrix NetScaler 10: Apply Citrix Receiver Theme

You may have noticed in the Release Notes of Citrix NetScaler 10 that is possible to apply the new Citrix Receiver theme to the Access Gateway Enterprise logon page.

As per the Release notes:

Apply the Citrix Receiver theme to the logon page
You can use the command line to overwrite the original Access Gateway logon page with the Citrix Receiver theme

Only the how is nowhere to be found in the Citrix documentation. Update: the official Citrix product documentation on how to apply the Citrix Receiver theme to Citrix Access Gateway Enterprise 10 can be found here:
http://support.citrix.com/proddocs/topic/access-gateway-10/agee-client-connect-cr-new-theme-page-tsk.html
So, although the explanation below will work, I’d have to recommend using Citrix product documentation.

Well, Jarian Gibson found out how (So no credit for me), you can also go tot the forum post, it is the same task sequence.
