# ls-remote
“Pull Request Refs” which we use to look at the raw references on the server.

# ls-files
“Manual File Re-merging”, “Rerere” and “The Index” to take a more raw look at what your staging area looks like.

# rev-parse
“Branch References” to take just about any string and turn it into an object SHA-1.
