 mkdir bin
 cd bin

 chmod a+x repo
 cd ..
}}}
Get replicant 2.2

 cd replicant-2.2
 ../bin/repo init -u git://gitorious.org/replicant/manifest.git -b replicant-2.2
 ../bin/repo sync
}}}

== Each time you want to build replicant 2.2 ==
{{{
cd ~/replicant-2.2
 ../bin/repo sync
source build/envsetup.sh
export ANDROID_JAVA_HOME=$JAVA_HOME
lunch cyanogen_dream_sapphire-eng 
make -j$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc) bacon  #uses arguments like -j9 to speed up build in case of multi-core cpu
}}}
Don't forget the bacon at the end, without that you will have some build errors.
Note that the bacon also produces standard images like system.img, just ship or use the system.img like images
