This is a testbed for exposing moment to the world.
The package.sh takes the files from src/ and appends/prepends the necessarylines to make them cjs/esm compatible, and then outputs the results innode_modules/bmoment (so it looks like we npm-installed it -- similar to howour users will have it).
Then run
./package.shnode --version # 10.5.0node bmoment_test_cjs.jsnode --experimental-modules bmoment_test_esm.mjs
