-<h1> The <tt>s6-test</tt> program </h1>
-
-<p>
- s6-test evaluates an expression and indicates the result via its
-exit status.
-</p>
-
-<h2> Interface </h2>
-
-<pre>
- s6-test <em>expression...</em>
-</pre>
-
-<p>
- s6-test acts as the generic
-<a href="https://pubs.opengroup.org/onlinepubs/9699919799/utilities/test.html">test</a> utility,
-but it diverges from the specification on one point: if an argument starts with a backslash,
-this backslash is ignored (and the argument cannot be an operation). This is a simple
-disambiguation technique that has unfortunately not been chosen by the standard.
-</p>
-
-<p>
- s6-test accepts an arbitrary number of arguments.
-</p>
-
-<h2> Exit codes </h2>
-
-<ul>
- <li> 0: the test is true </li>
- <li> 1: the test is false </li>
- <li> 100: wrong usage </li>
- <li> 101: internal error (should never happen, warrants a bug-report) </li>
- <li> 111: system call failure </li>
-</ul>
-
-<h2> Posixness </h2>
-
-<p>
- s6-test <strong>is not</strong> suitable as a Single Unix
-<a href="https://pubs.opengroup.org/onlinepubs/9699919799/utilities/test.html">test</a>
-program; however, if your arguments never start with a backslash, it exhibits the
-exact same behaviour.
-</p>
-
-<h2> Non-standard expressions </h2>
-
-<ul>
- <li> <tt>-v&nbsp;<em>VAR</em></tt>&nbsp;: tests whether the
-<em>VAR</em> variable is defined in the current environment. </li>
- <li> <tt><em>string</em>&nbsp;=~&nbsp;<em>pattern</em></tt>&nbsp;:
-tries to match <em>string</em> against extended regular expression
-<em>pattern</em>. True if any part of <em>string</em> matches <em>pattern</em>;
-in order to match whole strings, you must anchor <em>pattern</em> with
-<tt>^</tt> and <tt>$</tt> markers. </li>
-</ul>
-
-<h2> Notes </h2>
-
-<ul>
- <li> <strong>This program is deprecated.</strong> It will disappear in a
-near future version of s6-portable-utils. You are encouraged to use
-<a href="https://skarnet.org/software/execline/eltest.html">eltest</a>
-instead, which has the same interface and functionality, and is a part of the
-<a href="https://skarnet.org/software/execline/">execline</a> package. </li>
-</ul>
