ef4/fast-sourcemap-concat

Fast Source Map Concatenation is a library designed to efficiently concatenate files, optionally including their pre-generated sourcemaps, and produce a single output file with an associated sourcemap. It is optimized for line-by-line concatenation, making it significantly faster than general-purpose source map libraries. This tool is primarily intended for use in Ember.js projects via ember-cli and broccoli-concat, catering to developers working with JavaScript build tools and source map management.
