+# A hook script to verify what is about to be pushed. Called by "git
+# push" after it has checked the remote status, but before anything has been
+# pushed. If this script exits with a non-zero status nothing will be pushed.
+#
+# This hook is called with the following parameters:
+#
+# $1 -- Name of the remote to which the push is being done
+# $2 -- URL to which the push is being done
+#
+# If pushing without using a named remote those arguments will be equal.
+#
+# Information about the commits which are being pushed is supplied as lines to
+# the standard input in the form:
+#
+# <local ref> <local sha1> <remote ref> <remote sha1>
