+The key object is a @code{Repository}, on which @code{Txn} (immutable
+transactions) and @code{MutTxn} (mutable transactions) can be started, to
+perform a variety of operations.
+
+Another important object is a @code{Patch}, which encodes two different pieces
+of information:
+
+@itemize
+@item Information about deleted and inserted lines between two versions of a
+file.
+@item Information about file moves, additions and deletions.
