+This directory and its children contain LibVEX, a library for dynamic
+binary instrumentation and translation.
+
+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.
+
+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.
+
+Please also read the information in the file LICENSE.README.
