+
+Usage:
+
+ gomvpkg -from <path> -to <path> [-vcs_mv_cmd <template>]
+
+Flags:
+
+-from        specifies the import path of the package to be moved
+
+-to          specifies the destination import path
+
+-vcs_mv_cmd  specifies a shell command to inform the version control system of a
+             directory move.  The argument is a template using the syntax of the
+             text/template package. It has two fields: Src and Dst, the absolute
+             paths of the directories.
+
+             For example: "git mv {{.Src}} {{.Dst}}"
+
+gomvpkg determines the set of packages that might be affected, including all
+packages importing the 'from' package and any of its subpackages. It will move
+the 'from' package and all its subpackages to the destination path and update all
+imports of those packages to point to its new import path.
+
+gomvpkg rejects moves in which a package already exists at the destination import
+path, or in which a directory already exists at the location the package would be
+moved to.
+
+gomvpkg will not always be able to rename imports when a package's name is changed.
+Import statements may want further cleanup.
+
+gomvpkg's behavior is not defined if any of the packages to be moved are
+imported using dot imports.
+
+Examples:
+
+% gomvpkg -from myproject/foo -to myproject/bar
+
+  Move the package with import path "myproject/foo" to the new path
+  "myproject/bar".
+
+% gomvpkg -from myproject/foo -to myproject/bar -vcs_mv_cmd "git mv {{.Src}} {{.Dst}}"
+
+  Move the package with import path "myproject/foo" to the new path
+  "myproject/bar" using "git mv" to execute the directory move.
