These files all have options that trip up the `nix-doc-munge` conversion tool for one reason or another (syntax that clashes with Markdown, options that were already using Markdown syntax despite not being marked that way, output that differs slightly after conversion, syntax too elaborate to convert with some cheap regular expressions, ...). Translate them manually and do a little copyediting to options in the vicinity while we're at it.

Because hie-nix is not packaged in Nixpkgs, you need to add it as an
|
|
overlay or set this option. Example overlay configuration:
|
|
|
|
```nix
|
|
${exampleOverlay}
|
|
```
|
|
'';
|
|
example = literalExpression ''
|
|
(import ~/src/haskell-ide-engine {}).hies + "/bin/hie-wrapper";
|
|
'';
|
|
};
