[libvirt] need help/clarification about git and patches.

Using git is more than a little different way of doing business for me. My usual way to create and apply a patch is to rebuild a src.rpm. This way I have a lot less changes of screwing something up because of ignorance. It it a little while but I finally cloned a copy of libvirt.git. I applied a patch to remove the "--filterwin2k" [one fixup because a test file changed slightly. I then ran "git diff" and produce a new patch. OK, now what? I did the "git commit" and then tried to do the "git send-email" like it says in your "hacking" document ... "git: 'send-email' is not a git command. I am going to do what I believe is the right thing to do and submit the patch but there needs to be a bit more info as to how we should do things. Gene
