# Usage: `deploy-npm-versioned $dst_dir`
#
# Builds the repository in the current directory with `npm run deploy` and copies the contents of `dist/` into multiple
# sub-directories in `$dst_dir`.
# The sub-directories are named after the version number listed in the `package.json`.
# If the version is `A.B.C`, then the repository is deployed into sub-directories `A.B.C`, `A.B.x`, and `A.x.x`, where
# `x` is literal.
