| `output`      | Webpack-ed dependencies                      |

### How to rerun the program

1. Collect the mineable repositories

    ```bash
    node src_dataset/index.mjs
    ```

    Look at the code and you can tweak the number of repos that are being used.
    
    They will get copied to `../cache-repos/repos`.
    `package.json` of each of the files are fetched from npm (so that we dont clone the whole repo) and cached in `../cache-repos`.
2. Get a list of candidate repos that can slice.

    ```bash
    ./script.sh
    ```

    If something goes wrong, add it to the ignore list.
    This also moves the repos into a `candidates/` folder.
    It will create `success.txt` with a list of repos that work with slicing.

3. Slice and get test results

    Go through `success.txt`, and run `master.sh` with each repo.

    `./master.sh cov` -> Get test coverage and pre-test count
    `./master.sh exec` -> Slice and post coverage
    `./master.sh cloc` -> Sliced statistics


    Note that in some cases, the scripts may attempt to execute tests in the backup node modules folder (`.node_modules`). In this case, move it out, and run the tests individually. You can get the commands from the output from the master script (which calls the `script-placer.sh` script).
