<!--
	DO NOT EDIT THIS FILE.
	IT WILL BE REPLACED WHEN FONTCONFIG IS UPDATED.
	LOCAL CHANGES BELONG IN 'local.conf'.

	The intent of this standard configuration file is to be adequate for
	most environments.  If you have a reasonably normal environment and
	have found problems with this configuration, they are probably
	things that others will also want fixed.  Please submit any
	problems to the fontconfig bugzilla system located at fontconfig.org

	Note that the normal 'make install' procedure for fontconfig is to
	replace any existing fonts.conf file with the new version.  Place
	any local customizations in local.conf which this file references.
