To create a new index from all of your files (note, subdirectories aren't

../shit/write-tree | ./hash-object -t tree -w
This will print the tree ID to stdout. Use that to make a commit:
export GIT_AUTHOR_NAME="Your Name"
../shit/commit-tree <tree sha> | ./hash-object -t commit -w
This will print out the new commit's SHA. To update master to point to this new
echo <commit sha> > .git/refs/heads/master
