* TODO (low priority)
enhance RPM packages for lttng kernel
-Integrate header generation (genevent) in kernel build system.
-Export channels via network sockets instead of writing them to disk.
Export buffers with time constraint for "live" visualisation. Use ltt_force_switch periodically from a timer to insure slow channels do not interfere with viewing.

* Need to be discussed
-Use 2.6.14 RelayFS control files.

drop ltt_filter_control, use functions pointers instead.
-Merge facilities headers into one big header.
-Change the name of XML files from XML to something else.
Remove ltt-base.c.
