Argument for "Excemption path"?

[tobbeThorn]

With typescript 4 we want to make 3 versions of our builds, normal dist with latest (4+) and allso 3.4 and 3.8 versions like:

  "typesVersions": {
    "<3.8": {
      "*": [
        "ts3.4/*"
      ]
    },
    ">=3.8 <4.0": {
      "*": [
        "ts3.8/*"
      ]
    }
  },

And the build script:

    "build": "tsc && downlevel-dts . ts3.4 --to=3.4 && cp tsconfig.json ./ts3.4/ && downlevel-dts . ts3.8 --to=3.8 && cp tsconfig.json ./ts3.8/ && rm -rf ./ts3.8/ts3.4",

Note: I have to remove files from ts3.4 in previous step ending up in ts3.8
If you see anything I did wrong with this I whould love to know. Else it whould be great with an optional argument that excempts files that we do not want to end up in the target.

Similar problem! But to re-use above scenario, the output after a build would be:

• dist/
• ts3.4/
  • dist/
• ts3.8/
  • dist/
  • ts.3.4/ <-- Not wanted!? Thus removed by last step in build script.

If we later add more versions tsX.Y, we will need to add several more rm to remove previous ts3.4, ts3.8 and so on, from tsX.Y.

• tsX.Y/
  • dist/
  • ts.3.4/ <-- rm
  • ts.3.8/ <-- rm
  • ts.... <-- rm

Correct? Better solution?
