Some docs include code snippets from examples. For example the HTTP README.adoc. We should investigate tooling to extract code from examples to avoid duplication and stale docs.

I think, for this we need tool like javasphinx

@shekhar-rajak we use antora for document generation. You can refer to antora documentation to get an idea about how to do this with antora.
