  //
  // The last object type is the simplest and requires the least parsing help. Blobs are just file
  // contents and can contain anything, there is no structure to it. The main advantage to using the
  // [simple blob api][ba] is that when you're creating blobs you don't have to calculate the size
  // of the content.  There is also a helper for reading a file from disk and writing it to the db and
  // getting the oid back so you don't have to do all those steps yourself.

  // ### Revwalking
  //
  // The libgit2 [revision walking api][rw] provides methods to traverse the directed graph created
  // by the parent pointers of the commit objects.  Since all commits point back to the commit that
  // came directly before them, you can walk this parentage as a graph and find all the commits that
  // were ancestors of (reachable from) a given starting point.  This can allow you to create `git log`
  // type functionality.

  // one or more starting points onto the walker.  If you want to emulate the output of `git log` you
  // would push the SHA of the commit that HEAD points to into the walker and then start traversing them.
  // You can also 'hide' commits that you want to stop at or not see any of their ancestors.  So if you

  git_repository_index(&index, repo);

  // For each entry in the index, you can get a bunch of information including the SHA (oid), path
