Hi, bug-gnu-utils!

I'm using diff 2.8.1.

I want to get a list of files which have changed between two
directories, say ~/orig and ~/new, and I want them in a form I can use
in a script.  For example, I would like to get this output

    cc-defs.el README

The nearest facility I can find is diff -q ~/orig ~/new, which gives
"user friendly" output thusly:

    Files ~/orig/cc-defs.el and ~/new/cc-defs.el differ
    Files ~/orig/README and ~/new/README differ

.  Have I missed a way of getting scriptable output, or do I need to
filter out the crud by hand?  Or can a later version give script
friendly output?

Thanks in advance?
