Note
The only version available on Hackage is largely outdated and shouldn't be used. This repository contains a WIP rewrite, that should make achille way easier to use and even more powerful.
achille is an embedded Haskell DSL for building incremental static site generators.
It has a very simple abstraction for composable build rules, a straightforward implementation and few dependencies.
For troubleshooting, general questions or suggestions, feel free to send a mail to the public mailing list ~flupe/achille@lists.sr.ht. Archives are available here.
