When snippets are read all source files are stored in a list. When searching for a snippet with a specified key, and that key is not found, the list of files are used as a secondary lookup. The lookup is done by finding all files that have a suffix matching the key. This results in the ability to include full files as snippets using the following syntax:
snippet: directory/FileToInclude.txt
The path syntax uses forward slashes /.
snippet: http://myurl

Add the following to the markdown:
include: theKey
