This file defines operations on the content of a document (text, parsing of sentences, scheduling).

The document manager holds the view that Coq has of the currently open states. It makes it easy for IDEs to handle text edits, navigate and get feedback. Note that it does not require IDEs to parse vernacular sentences.

The event manager is in charge of the actual event of tasks (as defined by the scheduler), caching event states and invalidating them. It can delegate to worker processes via DelegationManager

The scheduler is the component in charge of planning the execution of sentences. It also defines the task delegation strategy, and computes dependencies between tasks. Scheduling can be done incrementally.
