Exploit templates and mixins

Let's consider that you have written an exploit code for a new zero-day vulnerability. Now, to include the exploit code officially into the Metasploit Framework, it has to be in a particular format. Fortunately, you just need to concentrate on the actual exploit code, and then simply use a template (provided by the Metasploit Framework) to insert it in the required format. The Metasploit Framework offers an exploit module skeleton, as shown in the following code:
