Git alternatives to "svn info" that can be included in a build for traceability?

To complete Charles's answer, you also can make a script displaying "sn info" like information, like this one (already mentioned there)

#!/bin/bash

# author: Duane Johnson
# email: [email protected]

# license: MIT
# 
# Based on discussion at http://kerneltrap.org/mailarchive/git/2007/11/12/406496

pushd . >/dev/null

# Find base of git directory
while [ ! -d .git ] && [ ! `pwd` = "/" ]; do cd ..; done

# Show various information about this git directory
if [ -d .git ]; then
  echo "== Remote URL: `git remote -v`"

  echo "== Remote Branches: "
  git branch -r
  echo

  echo "== Local Branches:"
  git branch
  echo

  echo "== Configuration (.git/config)"
  cat .git/config
  echo

  echo "== Most Recent Commit"
  git --no-pager log  -n1
  echo

  echo "Type 'git log' for more commits, or 'git show' for full commit details."
else
  echo "Not a git repository."
fi
---
popd >/dev/null

Which would produce something like:

== Remote URL: origin [email protected]:canadaduane/my-project.git
== Remote Branches:
  origin/work
  trunk
  trunk@1309
  trunk@2570
  trunk@8

== Local Branches:
  master
* work

== Configuration (.git/config)
[core]
  repositoryformatversion = 0
  filemode = true
  bare = false
  logallrefupdates = true
[svn-remote "svn"]
  url = svn+ssh://svn.my-project.com/srv/svn
  fetch = my-project/trunk:refs/remotes/trunk
[remote "origin"]
  url = [email protected]:canadaduane/my-project.git
  fetch = refs/heads/*:refs/remotes/origin/*
[github]
  user = canadaduane
  repo = my-project

== Most Recent Commit

    Added changes to database schema that will allow decentralization from content pointers table

type 'git log' for more, or 'git show' for full commit details.

I know the answer is already accepted but this may help someone who is looking for remote and branch information.

 git remote show origin
