bizzach has asked for the wisdom of the Perl Monks concerning the following question:

My manager wants a document on the difference between Perl and Shell. Also, he is concerned that we are using a technology unsupported by Sun. He suggested that maybe we should do everything in Ksh. I didn't even know how to respond. I googled around but couldn't find anything. I'm hoping someone could point me toward documentation on the benefits of Perl. It needs to be a simple buy decisive document (for my manager).
