Is there an easy way to tell what commit a branch is branched off from?
Also, it there a way to tell what branch the branch is branched off
from?
I know I can use gitk to give a visual diagram, but I want something I
can feed into a program.
Thanks!

First you can check branch.<branchname>.merge configuration option
(with git-config) to check what branch (by _remote_ name) given branch
is based on.
Second, you can use "git merge-base <branchname> <second branch>" to
find common ancestor, i.e. branching point of two branches. By the
way, there is shortcut a..b and a...b for revision ranges: see
documentation in git-rev-parse (or was it git-rev-list?).
