Got those stinky read marks in your SIAKNG staining your transcript? worry not! run this on main/Academic/HistoryByTerm via console to hide those pesky marks!

Prerequisites:
* MSYS2 with MinGW64 environment.
* build tools: `pacman -S mingw-w64-x86_64-make mingw-w64-x86_64-cmake mingw-w64-x86_64-gcc mingw-w64-x86_64-winpthreads-git `
AV1 supports
* libsvtav1 (encoder): `pacman -S mingw-w64-x86_64-svt-av1`
* libdav1d (decoder): `pacman -S mingw-w64-x86_64-dav1d`
VVC supports
* libvvenc (encoder):

Installing Ocaml (latest w/o opam) in Windows via MSYS2

Installing OCaml (latest w/o opam) in Windows via MSYS2

  1. Preparation: MSYS2 MinGW64, make sure git, make, diffutils, and gcc installed, e.g. with pacman -S git make diffutils mingw-w64-x86_64-gcc.
  2. git clone https://github.com/ocaml/ocaml.git.
  3. git submodule update --init.
  4. ./configure, then make, and then install with make install.

At this point ocaml, ocamlc, and ocamlopt is already installed on the MSYS2 MinGW64 environment, but you'll hit by error like "Unbound module Stdlib".

  1. Check standard_library location via ocamlc -config, should be /mingw64/lib/ocaml.
