I'm attempting to examine a bundle of 79mb but I keep getting JavaScript heap out of memory. I gave it 16gb of memory to work with but it wasn't enough. Is this normal or is something else going on?

browserify-breakdown < _dist/js/index.min.js 
project/node_modules/browserify-breakdown/index.js:44
          level: level,

Can you add a repository field so it shows up? https://www.npmjs.com/package/browserify-breakdown

I usually don't trust packages that don't have a repo field, since it's too difficult to find the code. ;)

Great library, cheers!

$ npm install -g browserify-breakdown
$ browserify-breakdown
env: node\r: No such file or directory

If you convert the line endings to unix style, then this will start working for users on non-Windows systems, I believe. If you google for the error message, you can see how others resolved it. For example: nwutils/nw-builder#75

Unfortunately for me, on a Windows environment running:

Get-Content .\_Inc\0.common-factor.js | browserify-breakdown

Always throws an error:

I suspect that this is not a problem with acorn, but rather the encoding of the file when windows pipes it's contents to this script.

I might be able to avoid this whole thing by adding a gulp task to do this for me. I looked in the tests and it seems this library works with strings. Will it also work for streams? Maybe you could add some programmatic examples in the README (using gulp, using scripts).

it does work on the vendor.js from the same project, though, which is built using a similar browserify configuration.
