It adds option
--convert=flamegraph, which converts rbtrace output to format from which you could create flamegraph.It helped me to find a problem with timeout in DNS resolve, which was much harder to see with a sampling profiler.
After that I found that it is possible to make such a graph with ruby-prof(e.g. https://github.com/jlfwong/speedscope/wiki/Importing-from-ruby-prof)), but it would be nice if rbtrace also had this functionality.
