Forked Project

This project is forked from https://www.npmjs.com/package/variable-replacer.

The purpose of the fork was to introduce the following features :

dest argument : allow to clearly separate and make it optionnal.

Now when no argument is provided for dest, the dest path is equal to file source path.
