Hello, this is Dr. Bill.
Welcome back.

When it comes to website design and maintenance, one of the
most important things that you will need to learn is how
how to perform task automation.

Task automation can be accomplished using a scripting environment
like PowerShell or even a programing language like
Visual Basic.  

To really make task automation powerful, it needs to be recursive.
This means the code can call itself.  In other words, it recursively look through 
folders, and sub-folders within those folders, and sub-folders
within those sub-folders, and so on.

To illustrate task automation, we will start with a couple PowerShell 
examples and then look at an example using VBA.
