-Rollup tree-shaking test
-------------------------
-
-The purpose of this test is to verify how much stuff can be tree-shaken from our packages.
-
-The test generates an empty js file that imports everything from a particular package but doesn't
-use any of the imported references.
-
-In the ideal scenario Rollup should detect that none of the references are being used and should
-create an empty bundle file.
-
-In reality there is a lot of stuff preserved in the bundle because Rollup is currently not able to
-make a safe decision to remove many of the unused symbols.
-
-To run execute: `./tools/tree-shaking-test/test.sh`
-
-then inspect `dist/tree-shaking/test/**/*.bundle.js`
