-tazblog CLI
-===========
-
-My blog stores its content in DNS, spread out over three types of `TXT` entries:
-
-* `TXT _posts.blog.tazj.in.`: A sorted list of posts, serialised as a JSON list of
-  strings (e.g. `["1486830338", "1476807384"]`)
-
-* `TXT _chunks.$postID.blog.tazj.in`: JSON chunks containing the blog post text
-
-* `TXT _meta.$postID.blog.tazj.in`: JSON blob with blog post metadata
-
-All JSON blobs are base64-encoded.
-
-This CLI tool helps to update those records.
-
-Each blog post data is a series of JSON-encoded structures which follow one of
-these formats:
-
-```
-struct metadata {
-    chunks: int
-    title: string
-    date: date
-}
-```
-
-Where `chunks` describes the number of chunks following this format:
-
-```
-struct chunk {
-    c: int
-    t: string
-}
-```
-
-Writing a blog post to DNS means taking its text and metadata, chunking it up
-and writing the chunks.
-
-Reading a blog post means retrieving all data, reading the metadata and then
-assembling the chunks in order.
