polytonic Greek: this template transcludes {{lang}} with ISO 639-3 grc: {{lang|grc|{{{1}}}}}, invoking the :lang(grc) pseudo-class in MediaWiki:Common.css, selecting

font-family: Athena, Gentium, "Palatino Linotype", "Arial Unicode MS", "Lucida Sans Unicode", "Lucida Grande", Code2000;

This template has been tested with Firefox, Internet Explorer 0.7 and Opera and works properly.

NOTE: As of July 23, 2010, there are no more fonts in Common.css. Polytonic fonts are in MediaWiki:Common.css/WinFixes.css, included from MediaWiki:Common.js; however, the language-specific declarations are no longer there. (Where are they???)
