asar
Simple extensive tar-like archive format with indexing
Asar is a simple extensive archive format, it works like tar that concatenates all files together without compression while having random access support. You can pass in a transform option, which is a function, that either returns nothing or a stream. Transform. The latter will be used on files that will be in the .asar file to transform them. There is also an unofficial grunt plugin to generate asar archives at bwin/grunt-asar.
