According to the documentation:
--inlineSourceMap and inlineSources command line options: --inlineSourceMap will include source map files within the generated .js files rather than in a separate .js.map file. --inlineSources allows for the source .ts file to be included within the .js file as well.
Does this mean that the entire source files are written to the outputFile? What is the benefit of doing this? After all, you can use the sourcemaps to recreate the original sources if needed.
