POST-INSTALL After upgrading fontconfig, always run rejmerge and upgrade /etc/fonts.conf and /etc/fonts.dtd. /etc/fonts/conf.avail ships with configuration snippets that can be symlinked from /etc/fonts/conf.d to enable them. It's recommended to use these snippets instead of duplicating XML code in your /etc/fonts/local.conf. For more information on conf.avail/conf.d, please see: http://gitweb.freedesktop.org/?p=fontconfig;a=blob_plain;h=dbcfe2135f809089266fbbb024a2304f6c24ac03;f=conf.d/README
