6: I. Intro
7: Before starting any work on ELWIX must we prepare environment.
8:
9: What this means ::
10: - We must downloading freebsd sources from CVS/SVN repository and put on separate place from /usr/src.
11: Set in config/rc.elwix variable BSDSRC="..." with place where you get freebsd sources.
12: - We gather from ELWIX CVS repository kodicom_mux project. After this we need to patch our freebsd
13: sources like that "cd <where you put freebsd sources>; patch -p0 < <kodicom_mux/contrib/kodicom.patch>"
14: - We must checkout from ELWIX CVS repository core libraries "libait*" , "embedtools", "embedaddons"
15: and GPLv2 "gpl/*" projects
16: - Optional download of 3th party software for ELWIX firmware. Project name is embedaddon from ELWIX CVS
