+<h1> The <tt>forstdin</tt> program </h1>
+
+<p>
+<tt>forstdin</tt> uses its input as loop elements to
+run another program.
+</p>
+
+<h2> Interface </h2>
+
+<p>
+ In an <a href="execlineb.html">execlineb</a> script:
+</p>
+
+<pre>
+ forstdin [ -p | -o <em>okcodes</em> | -x <em>breakcodes</em> ] [ -n ] [ -C | -c ] [ -0 | -d <em>delim</em> ] <em>variable</em> <em>loop...</em>
+</pre>
+
+<ul>
+ <li> <tt>forstdin</tt> reads its standard input as it becomes available,
+<a href="el_transform.html#split">splitting</a> it automatically. </li>
+ <li> For every argument <em>x</em> in the split output,
+<tt>forstdin</tt> runs <em>loop...</em> as a child process, with
+<em>variable</em>=<em>x</em> added to its environment. </li>
+ <li><tt>forstdin</tt> then exits 0.
+</ul>
+
+<h2> Options </h2>
+
+<ul>
+ <li> <tt>-p</tt>&nbsp;: parallel mode. Do not wait for a <em>loop...</em>
+instance to finish before spawning the next one. <em>forbacktickx</em> will
+still wait for all instances of <em>loop</em> to terminate before
+exiting, though. </li>
+ <li> <tt>-0</tt>&nbsp;: accept null characters on its stdin,
+using them as delimiters. If this option and a <tt>-d</tt> option are
+used simultaneously, the rightmost one wins. </li>
+ <li> <tt>-o</tt>&nbsp;<em>okcodes</em>&nbsp;: <em>okcodes</em> must
+be a comma-separated list of exit codes. If the <tt>-p</tt> flag
+hasn't been given and <em>loop</em> exits with one of the codes in
+<em>okcodes</em>,
+forstdin will run the following instances of the loop, but if the exit code is
+not listed in <em>okcodes</em>, forstdin will exit immediately with an
+<a href="exitcodes.html">approximation</a> of the same exit code. </li>
+ <li> <tt>-x</tt>&nbsp;<em>breakcodes</em>&nbsp;: like the previous
+option, but with inverted meaning - the listed exit codes are codes
+that will make forstdin break the loop and exit, and the unlisted exit
+codes will make it keep looping. </li>
+ <li> Other options are used to <a href="el_transform.html">control
+the substitution mechanism</a> for every <em>x</em>. Of course, you can't
+split <em>x</em>. </li>
+</ul>
+
+<h2> Notes </h2>
+
+<ul>
+ <li> You can start <em>loop...</em> with "import -u <em>variable</em>"
+to perform variable substitution. </li>
+</ul>
