   Custom Haskell handlers for Nginx▲98

   This is rather a mature project. It began out of curiosity: I wanted to test if Haskell FFI was powerful and expressive enough to interconnect C and Haskell code flawlessly. Particularly, if C strings generated inside Nginx can be shared within Haskell code and what must be done to respect their lifetimes etc. Recently, I released version 3.2.0 with revamped README (with a lot of examples) and a new approach to building Haskell handlers using the modernized cabal v2-build for dependencies.

    Merry Christmas, everyone! Now you can compile Haskell code on Windows 11 ARM. It will run full speed if you use UTM/QEmu on Apple silicon. :-) It's a very draft version, but it works well. Any ideas?
