Building

$3

You can build the exact same bytecode using Docker

`bash
npm run compile
`

Then check that all the files are the same using npm diff

`bash
npm diff
``

If the output is empty then the bytecode is the same as the one I published on NPM.

Each time I release a new version on GitHub, the GitHub's CI clones the GitHub repository, reproduces the build, and throws an error if the NPM release is different. If a version is present on NPM but not on GitHub, do not use it!
