# axtls CONFIG MINI-HOWTO
#
# Note: axtls is highly configurable and uses mconf, like the linux kernel.
# You can configure it in a couple of ways:
#
# 1) USE="-savedconfig" and set/unset the remaining flags to obtain the features
# you want, and possibly a lot more.
#
# 2) You can create your own configuration file by doing
#
#	FEATURES="keepwork" USE="savedconfig -*" emerge axtls
#	cd /var/tmp/portage/net-libs/axtls*/work/axTLS
#	make menuconfig
#
# Now configure axtls as you want.  Finally save your config file:
#
#	cp config/.config /etc/portage/savedconfig/net-libs/axtls-${PV}
#
# where ${PV} is the current version.  You can then run emerge again with
# your configuration by doing
#
#	USE="savedconfig" emerge axtls
