Convert HTML Text to an EML File

Demonstrates Mht.HtmlToEMLFile, which creates an EML MIME message from an in-memory HTML string and saves it to a file.

The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background. The EML output is a MIME email message containing the HTML page and its referenced resources, suitable for sending the page as an HTML email.
