_confread is an internal script used for parsing /etc/ipsec.conf into a canonical format.
_confread is going to be obsoleted in the next major release of Openswan in favour of the addcon code. The new code will load all the connections much faster then the current scripts that can takes minutes to load a few hunderd conns, and requires awk and sed commands not always available in their full versions, such as with busybox on embedded platforms. The old alternative to this called starter will also be removed as obsolete for the new addcon code.
