+DEFAULT_LIBRARIES=<comma separated list of library ids that will be subscribed by default: "abc123,def456">

+
+To disable Patreon features and unlock all paid restrictions for all users of your deployment, replace
+`"patreon": { "clientId": ... }"` with `"disablePatreon": true` in the public key of the METEOR_SETTINGS environment variable.
+
+Alternatively run `meteor run --settings exampleMeteorSettings.json` to start the app with the example settings that disable Patreon by default.
+
 Now, visiting [](http://localhost:3000/) should show you an empty instance of
 DiceCloud running.

-/**
- * This function is the heart of DiceCloud. It recomputes a creature's stats,
- * distilling down effects and proficiencies into the final stats that make up
- * a creature.
- *
- * Essentially this is a depth first tree traversal algorithm that computes
- * stats' dependencies before computing stats themselves, while detecting
- * dependency loops.
- *
- * At the moment it makes no effort to limit recomputation to just what was
- * changed.
- *
- * Attempting to implement dependency management to limit recomputation to just
- * change affected stats should only happen as a last resort, when this function
- * can no longer be performed more efficiently, and server resources can not be
- * expanded to meet demand.
- *
- * A brief overview:
- * - Fetch the stats of the creature and add them to
- *   an object for quick lookup
- * - Fetch the effects and proficiencies which apply to each stat and store them with the stat
- * - Fetch the class levels and store them as well
- * - Mark each stat and effect as uncomputed
- * - Iterate over each stat in order and compute it
- *   - If the stat is already computed, skip it
- *   - If the stat is busy being computed, we are in a dependency loop, make it NaN and mark computed
- *   - Mark the stat as busy computing
- *   - Iterate over each effect which applies to the attribute
- *     - If the effect is not computed compute it
- *       - If the effect relies on another attribute, get its computed value
- *       - Recurse if that attribute is uncomputed
- *     - apply the effect to the attribute
- *   - Conglomerate all the effects to compute the final stat values
- *   - Mark the stat as computed
- * - Write the computed results back to the database
