Adding comments to a PowerShell script is as simple as adding the
# character at the beginning of the line. To comment out entire blocks of code, you start a comment block with the
<# character and terminate the comment block with the
#> character, as shown in the following example:
<#The is the area containing thecomments in you comment block.#>
Another way to comment out blocks of code is to use something called a here string. This technique is not covered in this book.
