+### @usage: TS_PACKAGE()
+###
+### The TypeScript/JavaScript library module, that does not need any compilation,
+### and is just a set of files and NPM dependencies. List required files in TS_FILES macro.
+### `package.json` is included by default.
+###
+### @example
+###
+###     TS_PACKAGE()
+###         TS_FILES(
+###             eslint.config.json
+###             prettierrc.json
+###         )
+###     END()
