File 0001-locale-support-in-papersize-definition.patch of Package groff
From 15c71e2588058f20169440c0add955a527144c7a Mon Sep 17 00:00:00 2001 From: Michal Vyskocil <mvyskocil@suse.cz> Date: Mon, 26 Sep 2011 13:23:56 +0200 Subject: [PATCH] locale support in papersize definition The papersize definition in groff_font(5) has been extended by new keyword "locale". In this mode groff determine the paper size from LC_PAPER variable. The algorithm is simple - there is a small static list of countries using letter based on territory language information page [1] (CLDR 2.0). If the LC_PAPER contains the country code (for instance _CL - Chile), letter dimmensions are used. Otherwise a4.
