opt/fontconfig

POST-INSTALL

  /usr/share/fontconfig/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:
