+Each key under `action` defines an action that can be taken for the source. A source must at least have a `fetch` action.

+Each key under `env` defines an environment variable that will be set when `fetch` or other actions are executed.
 
 If `cron` is present, it must define a crontab schedule. Intake will automatically create crontab entries to update each source according to its cron schedule.
 
+`batch` may be a number or string of a number. If it is present, items created by the source will be batched via `tts` so that all items created in a single 24-hour window become visible at the same time. Items created with a longer `tts` will keep their `tts`.
+
+The batch window is computed from midnight to midnight UTC, offset by the value of `batch` (in seconds).

 ## Interface for source programs
 
 Intake interacts with sources by executing the actions defined in the source's `intake.json`. The `fetch` action is required and used to check for new feed items when `intake update` is executed.
 
-To execute an action, intake executes the `exe` program for the action with the corresponding `args` (if present) as arguments. The process's working directory is set to the source's folder, i.e. the folder containing `intake.json`. The process's environment is as follows:
