Document last modified date in Reverb

In WebWorks Reverb 2.0, there is a target setting that allows you to display the Last modified date of each document in your generated output pages. If you enable this target setting, your end-users will be able to see the date of that last time the document that generated a particular page was edited. If you examine the image below, you can see the date string in a light colored gray.

Note: When this setting is enabled, Reverb 2.0 prefers an authored date over the file-system modified date. If a page's source has a date marker (such as a Markdown++ front matter date key, matched case-insensitively), that value is used. This is more accurate for assembled Markdown++ sources, where the file-system date often reflects the assembly document rather than the individual topic. When no date marker is present, the file-system modified date is used as before.
