<h1> The s6-tai64n program </h1>
<p>
s6-tai64n acts as a filter, reading from stdin and writing to stdout.
It prepends lines with a
<a href="http://skarnet.org/software/skalibs/libstddjb/tai.html#timestamp">TAI64N
timestamp</a> and a space.
</p>
<h2> Interface </h2>
<pre>
s6-tai64n
</pre>
<ul>
<li> s6-tai64n exits 0 when it sees the end of stdin. If there's an
unfinished line, s6-tai64n processes it, adds a newline character to it,
and writes it before exiting. </li>
</ul>
<h2> Notes </h2>
<p>
s6-tai64n does neither "line buffering" nor "block buffering". It does
<em>optimal buffering</em>, i.e. it flushes its output buffer every time
it risks blocking on input. Every filter should behave this way, whether
its output is a tty or not: it's simpler and more efficient in every
case.
