I added the code line below in local.xml with link to google, but we do not want to rely on an external url.
<action method="addLinkRel"><rel>stylesheet</rel><href>//fonts.googleapis.com/css?family=Open+Sans</href></action>
So, we installed the "Open Sans" fonts-family (10 fonts) in skin/frontend/default/(our theme)/fonts.
What are the code lines we must add in local.xml to call multiple fonts from our local theme?
