+OUTPUT
+------
+
+The output of "git push" depends on the transport method used; this
+section describes the output when pushing over the git protocol (either
+locally or via ssh).
+
+The status of the push is output in tabular form, with each line
+representing the status of a single ref. Each line is of the form:
+
+-------------------------------
+ <flag> <summary> <from> -> <to> (<reason>)
+-------------------------------
+
+flag::
+ A single character indicating the status of the ref. This is
+ blank for a successfully pushed ref, `!` for a ref that was
+ rejected or failed to push, and '=' for a ref that was up to
+ date and did not need pushing (note that the status of up to
+ date refs is shown only when `git push` is running verbosely).
+
+summary::
+ For a successfully pushed ref, the summary shows the old and new
+ values of the ref in a form suitable for using as an argument to
+ `git log` (this is `<old>..<new>` in most cases, and
+ `<old>...<new>` for forced non-fast forward updates). For a
+ failed update, more details are given for the failure.
+ The string `rejected` indicates that git did not try to send the
+ ref at all (typically because it is not a fast forward). The
+ string `remote rejected` indicates that the remote end refused
+ the update; this rejection is typically caused by a hook on the
+ remote side. The string `remote failure` indicates that the
+ remote end did not report the successful update of the ref
+ (perhaps because of a temporary error on the remote side, a
+ break in the network connection, or other transient error).
+
+from::
+ The name of the local ref being pushed, minus its
+ `refs/<type>/` prefix. In the case of deletion, the
+ name of the local ref is omitted.
+
+to::
+ The name of the remote ref being updated, minus its
+ `refs/<type>/` prefix.
+
+reason::
+ A human-readable explanation. In the case of successfully pushed
+ refs, no explanation is needed. For a failed ref, the reason for
+ failure is described.
