+git-mv(1)
+=========
+
+NAME
+----
+git-mv - Script used to move or rename a file, directory or symlink.
+
+
+SYNOPSIS
+--------
+'git-mv' [-f] [-n] <source> <destination>
+'git-mv' [-f] [-k] [-n] <source> ... <destination directory>
+
+DESCRIPTION
+-----------
+This script is used to move or rename a file, directory or symlink.
+In the first form, it renames <source>, which must exist and be either
+a file, symlink or directory, to <destination>, which must not exist.
+In the second form, the last argument has to be an existing
+directory; the given sources will be moved into this directory.
+
+The index is updated after successful completion, but the change must still be
+committed.
+
+OPTIONS
+-------
+-f::
+ Force renaming or moving even targets exist
+-k::
+ Skip move or rename actions which would lead to an error
+ condition. An error happens when a source is neither existing nor
+ controlled by GIT, or when it would overwrite an existing
+ file unless '-f' is given.
+-n::
+ Do nothing; only show what would happen

+In the first form, source must exist and be either a file,

+Updates the git cache to reflect the change.
