/**
* This script ensures that the pinned version of devtools-protocol in
* package.json is the right version for the current revision of Chromium that
* Puppeteer ships with.
*
* The devtools-protocol package publisher runs every hour and checks if there
* are protocol changes. If there are, it will be versioned with the revision
* number of the commit that last changed the .pdl files.
*
* Chromium branches/releases are figured out at a later point in time, so it's
* not true that each Chromium revision will have an exact matching revision
* version of devtools-protocol. To ensure we're using a devtools-protocol that
* is aligned with our revision, we want to find the largest package number
* that's <= the revision that Puppeteer is using.
*
* This script uses npm's `view` function to list all versions in a range and
* find the one closest to our Chromium revision.
