Usage: mjs2cjs <start_file>
mjs2cjs uses a generic rollup.config.mjs to generate a commonjs file in
dist subdirectory.
Output name is extracted from package.json (field "main") or fallback to
index.cjs
Options:
-b ("bundle"): build a bundle file
-o ("out"): outfile
-a ("auto"): automatically transform "type:module" package into mix cjs/mjs
Note for "-a" option:
This option not only build commonjs file but also modify package.json. And if
a debian/index.cjs exists, it is installed and used in
"package.json->exports->require" field. This permits one to write a wrapper
when API change.
Option "-a" is usable if and only if module is a pure ES module (declared as
type:module in package.json).
