<h2>SYSTEM RESOURCES</h2>
By default, the max amount of CPU time allowed is 10 seconds, and any files
created cannot be larger than 5,000,000 bytes.
These limits are enforced using setrlimit(), and a core dump occurs when
limits are exceeded. These limits may be modified using a
<a href="config.html">
config file
</a>
or by modifying pl.h
