  s6 is a small suite of programs for UNIX, designed to allow process supervision
 (a.k.a service supervision),
 in the line of <a href="http://cr.yp.to/daemontools.html">daemontools</a>
-and <a href="http://smarden.org/runit/">runit</a>.
+and <a href="http://smarden.org/runit/">runit</a>, as well as various
+operations on processes and daemons. It is meant to be a toolbox for
+low-level process and service administration, providing different sets of
+independent tools that can be used within or without the framework, and
+that can be assembled together to achieve powerful functionality with
+a very small amount of code.
 </p>
 
 <p>
+ Examples of things you can do by assembling together several programs
+provided by s6:
+</p>
+
+<ul>
+ <li> <a href="http://en.wikipedia.org/wiki/Syslog">syslogd</a> functionality,
+using much less resources than the traditional syslogd. </li>
+ <li> Reliable service readiness notification, which is the basis for
+service dependency management. </li>
+ <li> Controlled privileged gain as with
+<a href="http://en.wikipedia.org/wiki/Sudo">sudo</a>, without using
+any suid programs. </li>
+ <li> The useful parts of
+<a href="http://0pointer.de/blog/projects/socket-activation.html">socket
+activation</a><sup><a href="#fn1" id="r1">[1]</a></sup>
+without having to change application code or link servers
+against any specific library, and without having to switch to any
+specific init system. </li>
+</ul>

  The s6 documentation tries to be complete and self-contained; however,

 confused at first. See the <a href="#related">related resources</a> section
