-   "This module implements fetching of individual blog entries from DNS.
-   Yes, you read that correctly.
-
-   Each blog post is stored as a set of records in a designated DNS
-   zone. For the production blog, this zone is `blog.tazj.in.`.
-
-   A top-level record at `_posts` contains a list of all published
-   post IDs.
-
-   For each of these post IDs, there is a record at `_meta.$postID`
-   that contains the title and number of post chunks.
-
-   For each post chunk, there is a record at `_$chunkID.$postID` that
-   contains a base64-encoded post fragment.
-
-   This module implements logic for assembling a post out of these
-   fragments and caching it based on the TTL of its `_meta` record.")
