Hi Sam,

At the kernel summit, people seemed to be interested to have the basic
userspace tools required to extract and pretty-print a trace available
within the kernel tree. Therefore, what I am trying to do is something
along the lines of

ltt/usr/
ltt/usr/tracectl/    (control tracing)
ltt/usr/tracesplice/ (splice buffers to disk)
ltt/usr/tracecat/    (merge sort and format the binary buffers into
                      human-readable text)

That would however require to create a Makefile which behaves a little
bit like what scripts/ is currently doing with hostprogs-y, only that
it's different in the sense that those tools are not required to build
the kernel and this could therefore become a more standard part of the
build process than what scripts/ is.

Is there some magic statements to put in Makefile and ltt/Makefile to
get this to build nicely with the rest of the tree ?

Thanks,

Mathieu
