+<h1> The <tt>s6-frontend-helper-echo</tt> internal program </h1>
+
+<p>
+ <tt>s6-frontend-helper-echo</tt> is a small utility to echo arguments to stdout.
+It is not meant to be called directly,
+although nothing bad will happen if you do. It is used in command lines crafted by
+<a href="s6_live.html#status">s6 live status</a> instead of the POSIX
+<a href="https://pubs.opengroup.org/onlinepubs/9799919799/utilities/echo.html">echo</a>
+program, because implementations of <tt>echo</tt> are infamously inconsistent with
+regards to options and arguments starting with a dash, so it's better not to rely on
+them at all.
+</p>
+
+<p>
+ <tt>s6-frontend-helper-echo</tt> is basically a copy of
+<a href="//skarnet.org/software/s6-portable-utils/s6-echo.html">s6-echo</a> and
+behaves exactly the same. The program has been included in s6-frontend in order to avoid
+a dependency to <a href="//skarnet.org/software/s6-portable-utils/">s6-portable-utils</a>.
