filewatcher -> buildin outfile problem

Hi,

I was happy with the Typescript Filewatcher. The option was

--outFile $FileNameWithoutExtension$.js

Now I can't squeeze the original Filename into the tsconfig.json.

root
  basis.ts
  basis2.ts
--Ordner1
     machwas.ts   imports basis.ts
    ->machwas.js
--Ordner2
     machanderes.ts imports basis2.ts
    -> machanderes.js

My aim is to create different Webpages with independent folder which compile from Files in the root-file.
It seems not to work with the build-in compiler.

My tsconfig:

{
  "compilerOptions": {
    "module": "commonjs",
    "target": "es5",
    "sourceMap": true,
    "outFile": "file.js", //what to write?
  },
  "exclude": [
    "node_modules"
  ]
}

Mit lieben Grüßen,

Uli Strautz
