-This file provides two functions for dealing with bio metadata. The
-functions are:
-
- -  __`processBio(content)` :__
-    Processes `content` to extract any frontmatter. The returned
-    object has two properties: `text`, which contains the text of
-    `content` sans-frontmatter, and `metadata`, which is an array
-    of key-value pairs (in two-element array format). If no
-    frontmatter was provided in `content`, then `metadata` will be
-    an empty array.
-
- -  __`createBio(note, data)` :__
-    Reverses the process in `processBio()`; takes a `note` and an
-    array of two-element arrays (which should give keys and values)
-    and outputs a string containing a well-formed bio with
-    frontmatter.

-
-                                       To my lovely code maintainers,
-
-  The syntax recognized by the Mastodon frontend for its bio metadata
-  feature is a subset of that provided by the YAML 1.2 specification.
-  In particular, Mastodon recognizes metadata which is provided as an
-  implicit YAML map, where each key-value pair takes up only a single
-  line (no multi-line values are permitted). To simplify the level of
-  processing required, Mastodon metadata frontmatter has been limited
-  to only allow those characters in the `c-printable` set, as defined
-  by the YAML 1.2 specification, instead of permitting those from the
-  `nb-json` characters inside double-quoted strings like YAML proper.
-    ¶ It is important to note that Mastodon only borrows the *syntax*
-  of YAML, not its semantics. This is to say, Mastodon won't make any
-  attempt to interpret the data it receives. `true` will not become a
-  boolean; `56` will not be interpreted as a number. Rather, each key
-  and every value will be read as a string, and as a string they will
-  remain. The order of the pairs is unchanged, and any duplicate keys
-  are preserved. However, YAML escape sequences will be replaced with
-  the proper interpretations according to the YAML 1.2 specification.
-    ¶ The implementation provided below interprets `<br>` as `\n` and
-  allows for an open <p> tag at the beginning of the bio. It replaces
-  the escaped character entities `&apos;` and `&quot;` with single or
-  double quotes, respectively, prior to processing. However, no other
-  escaped characters are replaced, not even those which might have an
-  impact on the syntax otherwise. These minor allowances are provided
-  because the Mastodon backend will insert these things automatically
-  into a bio before sending it through the API, so it is important we
-  account for them. Aside from this, the YAML frontmatter must be the
-  very first thing in the bio, leading with three consecutive hyphen-
-  minues (`---`), and ending with the same or, alternatively, instead
-  with three periods (`...`). No limits have been set with respect to
-  the number of characters permitted in the frontmatter, although one
-  should note that only limited space is provided for them in the UI.
-    ¶ The regular expression used to check the existence of, and then
-  process, the YAML frontmatter has been split into a number of small
-  components in the code below, in the vain hope that it will be much
-  easier to read and to maintain. I leave it to the future readers of
-  this code to determine the extent of my successes in this endeavor.
-
-  UPDATE 19 Oct 2017: We no longer allow character escapes inside our
-  double-quoted strings for ease of processing. We now internally use
-  the name "ƔAML" in our code to clarify that this is Not Quite YAML.
-
-                                       Sending love + warmth eternal,
-                                       - kibigo [@kibi@glitch.social]
