-Delta Object
-~~~~~~~~~~~~
-
-The "delta" object is used internally by the object database to
-minimise storage usage by using xdeltas (byte level diffs). Deltas can
-form chains of arbitrary length as RCS does (although this is
-configureable at creation time). Most operations won't see or even be
-aware of delta objects as they are automatically 'applied' and appear
-as 'real' git objects In other words, if you write your own routines
-to look at the contents of the object database then you need to know
-about this - otherwise you don't. Actually, that's not quite true -
-one important area where deltas are likely to prove very valuable is
-in reducing bandwidth loads - so the more sophisticated network tools
-for git repositories will be aware of them too.
-
-Finally, git repositories can (and must) be deltafied in the
-background - the work to calculate the differences does not take place
-automatically at commit time.
-
-A delta can be created (or undeltafied) with
-link:git-mkdelta.html[git-mkdelta] it's raw data cannot be accessed at
-present.
