+NAME
+----
+rtla - Real-time Linux Analysis tool
+
+SYNOPSIS
+--------
+*rtla* COMMAND [OPTIONS]
+
+DESCRIPTION
+-----------
+The rtla(1) is a meta-tool that includes a set of commands that aims to
+analyze the real-time properties of Linux. But instead of testing Linux
+as a black box, rtla leverages kernel tracing capabilities to provide
+precise information about the properties and root causes of unexpected
+results.
+
+COMMANDS
+--------
+*osnoise*::
+Gives information about the operating system noise (osnoise).
+*timerlat*::
+Measures the irq and thread timerlat latency.
+
+OPTIONS
+-------
+*-h*, --help
+	Display the help text.
+
+For other options, see the man page for the corresponding command.
+
+SEE ALSO
+--------
+_rtla-osnoise(1)_, _rtla-timerlat(1)_.
