Perl's Warn and Die Signals

This is a tutorial on using Perl's warn and die signals. It is based on a post I made some time ago, here, but covers more of the details and raises more of the pitfalls. In this tutorial I attempt to separate the warn and die signals from the OS signals, explain how they are used and what they can be used for, and explore the problems that can come up. At the end you will find a list of additional documents you should read. Note that I write this under the risky assumption that you are using Perl 5.6. This does not exclude you if you have an older version of Perl, as I believe everything holds for Perl 5.0 with the exception of -W and the warnings pragma
