Example

// node.js
const path = require("path");
const mume = require("@shd101wyy/mume");

// es6
// import * as mume from "@shd101wyy/mume"

async function main() {
  const configPath = path.resolve(os.tmpdir(), ".mume");

  // if no configPath is specified, the default is "~/.config/mume"
  // but only if the old location (~/.mume) does not exist
  await mume.init(configPath);
