{-# LANGUAGE CPP #-}

{-|
This module exports an API similar to pandoc-types' "Text.Pandoc.Builder", but
with the `simple*` versions as the default versions, and with a few extras
from "Text.Pandoc.Builder.Monadic.Veneer".

In general, Builder.simple{a} becomes Builder.Monadic.{a} and Builder.{a}
becomes Builder.Monadic.{a}'.

If you want to match the "Text.Pandoc.Builder" API more precisely, you can use
"Text.Pandoc.Builder.Monadic.Verbatim" instead.
