+ \item Created in 1999, by Prof. Paolo Mantegazza, Politecnico di

+ \item Initially attracted the community of contributors frustrated
+ by the RTLinux legal issues.
+ \item But only actively maintained on x86. Very low activity on the
+ mailing list.
+ \item The community of users and developers switched to Xenomai.
\item May offer slightly better latencies than Xenomai, at the
- expense of a less maintainable and less portable code base
- \item Since RTAI is not really maintained on ARM and other embedded
- architectures, our presentation is focused on Xenomai.
