Hi Lawrence

You have been posting changes for some time now, and I would like to try
them. I have not done a build yet, just used your precompiled archive
files up to now. Can I do a build using the instructions in
mythtv_for_rpi.txt, substituting the github repo for the
www.softsystem.co.uk repo? Must I still use mythbuild.sh or can I use
./configure and make? Is mythbuild.sh now in github? Can the same github
branch be built for x86_64 and for arm?

Thanks
Peter
