-# usage
-
-All options aside fron the `pages`, `max`, and `forumla` options are passed
-on to the sparkline plugin.
-
-You don't need to specify any data points (though you can if you want to).
-Instead, data points are automatically generated based on the creation
-times of pages matched by the specified `pages` [[PageSpec]]. A maximum of
-`max` data points will be generated.
-
-The `formula` parameter controls the formula used to generate data points.
-Available forumlae:
-
-* `interval` - The height of each point represents how long it has been
- since the previous post.
-* `perday` - Each point represents a day; the height represents how
- many posts were made that day.
-* `permonth` - Each point represents a month; the height represents how
- many posts were made that month.
-* `peryear` - Each point represents a day; the height represents how
- many posts were made that year.
