<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> due to unreliable and
inconsistent handling of options and dash arguments in the various POSIX <a
href="https://pubs.opengroup.org/onlinepubs/9799919799/utilities/echo.html">echo</a>
implementations.
</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>.
