-Subject: [PATCH hurd 1/4] trans: add identity translator
-
-The 'identity' translator is the simplest possible translator.  It
-computes the identity function of Hurdish RPC translations.
-
-* trans/Makefile: Add new files.
-* trans/chroot.c: New file.
-* trans/chroot.h: Likewise.
-* trans/identity.c: Likewise.
