Merge Files Webpack Plugin

This webpack plugin merges multiple files output by extract-text-webpack-plugin (e.g., per-entry CSS files) into a single file. Version 1.1.2 is the latest; no new releases and no activity on GitHub since 2018. It requires webpack 2+ and extract-text-webpack-plugin 2+. Useful for combining CSS from multiple entries, but limited to legacy webpack setups. Alternative: mini-css-extract-plugin (webpack 4+).
