+//! This module defines the instance snapshot subsystem of Rojo.
+//!
+//! It defines a way to define the instance tree of a project as a pure function
+//! of the filesystem by providing a lightweight instance 'snapshot' type, a
+//! method to generate minimal patches, and a method that applies those patches.
+//!
+//! The aim with this approach is to reduce the number of bugs that arise from
+//! attempting to manually update instances in response to filesystem updates.
+//! Instead of surgically identifying what needs to change, we can do rough
+//! "damage-painting", running our relatively fast snapshot function over
+//! anything that could have changed and running it through a diffing function
+//! to minimize the set of real changes.
+//!
+//! Building out a snapshot reconciler is mostly overkill for scripts, since
+//! their relationships are mostly simple and well-defined. It becomes very
+//! important, however, when dealing with large opaque model files and
+//! user-defined plugins.
