# Set "npm_config_yes=true" to prevent npx from prompting for confirmation
# before installing npm-check-updates. Ostensibly, the "--yes" flag can be
# passed to npx to achieve the same effect, but for some odd reason, I find that
# it causes npm-check-updates to act as if the "--upgrade" flag has not been
# passed to it.
