/**
 * Just a small command-line wrapper around the conventional-changelog npm module
 * (https://www.npmjs.com/package/conventional-changelog), which also prepends
 * changes to CHANGELOG.md.
 *
 * By default, this script will generate changes from relevant commits between the
 * most recent tag and HEAD. The `from` and `to` flags may be provided to control the range of
 * commits to process.
 *
 * Manually specify begin and end
 * $ ./changelog.js --from=e987ac40343d89d47b7b6cc1c5932fd55b30e18a --to=3f7ebde037d92f8d93c6a40c0d73f840cac08287
 * Run with default (latest tag...head)
 * $ ./changelog.js
