These are functions dealing with error handling and logging. They

allow you to define your own error handling rules, as well as modify

the way the errors can be logged. This allows you to change and

enhance error reporting to suit your needs.

</para>

<para>

With the logging functions, you can send messages directly to other

machines, to an email (or email to pager gateway!), to system logs,

etc., so you can selectively log and monitor the most important parts

of your applications and websites.

</para>

<para>

The error reporting functions allow you to customize what level and

kind of error feedback is given, ranging from simple notices to customized

functions returned during errors.
