-synopsis:        Pretty-print regions within source code files
-description:
-    Pretty-print @Region@s of source-code, i.e. snippets.
-    .
-    This is meant to mimic tooling available in rust and used by tools such as
-    @sarif-fmt@.
-    .
-    For example, focusing on a region within our README:
-    .
-    @
-    \   ┌─ README.md:32:8
-    \   │
-    \32 │   main = do
-    \   │ ╭────────^
-    \33 │ │   let
-    \34 │ │     region = Region
-    \35 │ │       { startLine = 32
-    \36 │ │       , endLine = Just 44
-    \37 │ │       , startColumn = Just 8
-    \38 │ │       , endColumn = Nothing
-    \39 │ │       }
-    \40 │ │
-    \41 │ │   -- Returns Nothing if file is missing/empty or region is invalid
-    \42 │ │   mSnippet <- snippetFromFile region "README.md"
-    \43 │ │
-    \44 │ │   traverse_ (putDoc . reAnnotate annToAnsi . prettySnippet) mSnippet
-    \   │ ╰────────────────────────────────────────────────────────────────────^
-    @
-    .
-    To see the code that produces this, and an image of the output (e.g. with
-    color), view the [README on Codeberg](https://codeberg.org/pbrisbin/snippet#readme).
