#
# Alternatives and their downsides would be:
# 1. import outside of pkg root
# - pkg is less portable
# 2. copy widgetry.js file into each package and update import path on build
# - not really any less hacky, since we're still transforming at build
# - an extra request for the client
# 3. use proper bundler like webpack and system.js:
# - They're all complex - conceptually and dependency-wise
# - We can't use AMD modules because it doesn't support `import.meta`
