<h2 class="chapter">36 System Utilities</h2>
<p>This chapter describes the functions that are available to allow you to
get information about what is happening outside of Octave, while it is
still running, and use this information in your program. For example,
you can get information about environment variables, the current time,
and even start other programs from the Octave prompt.
