4.11.7 Supply a Description Option
As an extension to the original Markdown spec from John Gruber, an option to be used when formulating an HTML meta description value may be provided as part of the description command, as in the following example:
{:description:L}
The following values (in either upper- or lower-case) are recognized.
- L - Use the Long Title field value, if available
- N - No description generatiion (the default)
- S - Summarize the Body of the Note
- T - Use the Teaser field value, if available
A Note containing this command may appear anywhere within a Collection, and be given any convenient and meaningful title.
Since a Note containing such a command is not meant to be read sequentially as part of the overall Collection, Notenik will generally skip such pages when formatting Streamlined Reading navigational elements.
