Well actually in practice this shouldn't matter much, since most of the binary file formats have well-specified headers, and probably there's no binary file format that starts with `/*`, so no replacement will happen on those files.

However let's suppose someone deploys all the versions of fwk to the same directory. Then, if we compute the same hash for a file `my-widget-package.js` regardless of the version specified in the header, then when deploying new version, the file will be overriden since the hash is the same, yet it will contain `Aria Templates 1.x.y+1` in the header while someone might hypothetically require `ariatemplates.1.x.y.js` in his app and then while debugging see that some packages are taken allegedly from new version of the framework -- this might be confusing.

Hence probably it's better to just include version and date in the main file, i.e. `ariatemplates.js`
