% <input>erl -heart -env HEART_KILL_SIGNAL SIGABRT ...</input></pre>
<p> If heart should <b>not</b> kill the Erlang runtime system, this can be indicated
- using the environment variable <c><![CDATA[HEART_NO_KILL]]></c>.
+ using the environment variable <c><![CDATA[HEART_NO_KILL=TRUE]]></c>.
This can be useful if the command executed by heart takes care of this,
for example as part of a specific cleanup sequence.
- If unset, the default behaviour will be to kill as described above.
+ If unset, or not set to <c><![CDATA[TRUE]]></c>, the default behaviour
+ will be to kill as described above.
