-History - by Roy Marples
-------------------------
-I became a Gentoo/Linux developer in 2004 and wrote the modular network
-scripts for the Gentoo baselayout package. baselayout is a collection of
-bash scripts to bring up your computer and its services.
-Then towards the end of 2005 I found myself as the primary maintainer
-for baselayout.
-
-At the start of 2007, baselayout-2 is announced to the world, re-writing the
-core of baselayout in C and allowing POSIX sh init scripts instead of
-forcing the use of bash. By Mid 2007 I have re-written everything, including
-init scripts, and alpha and pre baselayout-2 snapshots where put into Gentoo.
-Towards the end of 2007 I retired as a Gentoo developer for reasons I won't
-go into here. baselayout-2 was still in the pre stage, and aside from the
-fbsd users, it was masked everywhere. However, I also desired to keep the
-baselayout-2 project alive, but outside of Gentoo and into other projects
-such as FreeBSD.
-
-As such, the Gentoo Council have allowed the creation of OpenRC under the
-2 clause BSD license, managed by me as an external project.
