+This directory contains the Vex dynamic translation library that
+underlies Valgrind.  With the exception of the following five files,
+all files are copyright OpenWorks LLP, and are licensed under the GNU
+GPL version 2 (see COPYING).
+
+  test/test-i386.c           (Fabrice Bellard, GNU GPL)
+  test/test-amd64.c          (Fabrice Bellard, GNU GPL))
+  switchback/linker.c        (University of Glasgow, BSD-style license)
+  switchback/test_emfloat.c  (BYTE magazine, public domain?)
+  switchback/test_ppc_jm1.c  (Jocelyn Mayer, BSD-style license)
+
+Changes: if you wish to contribute a change which is a significant one
+in terms of the amount of code changes, please be aware that OpenWorks
+LLP wishes to retain copyright of the Vex library.  Therefore you will
+have to sign over copyright ownership of your code to OpenWorks LLP
+before we can include your changes in the main source tree.
+
+Finally, before you start modifying anything for real, you should
+probably join the valgrind-developers mailing list and send it mail
+describing what you want to do and how you want to do it so you don't
+waste time working on something we can't integrate. This also allows
+us to keep track of what's being worked on so efforts aren't
+duplicated.
