The opposite of `tee` command, combining stdout/stderr from multiple commands and kill them with one signal (Ctrl+C).

```
-> command 1 stream ─┐
-> command 2 stream ─┤
                     └─ stdout/stderr/SIGINT to kill both
```

It means, you can write 2 parallel jobs in 1 npm script!!

```js
// package.json
{
    "scripts": {
        "start": "too --cmd 'rails s' --cmd 'webpack'"
        // Start server and client HMR in parallel,
        // and you can kill both by one Ctrl+C!!
    },
}
```

# Why?

Sometimes we do that,

```sh
% nohup rails server &
% nohup npm start-webpack &

# after you did some work

% pkill rails
% pkill webpack
```

I don't wanna do this any more, just wanna run multiple processes and kill them with one `Ctrl+C`!

# Usage

```sh
% too --cmd 'rails server' --cmd 'npm start-webpack'
```

Then you will get

```sh
[0] rails   # Rails log here
[1] npm     # NPM log here

# And you can kill both by one `Ctrl+C` (SIGINT)
```

# Too files

Or you can define your tasks on a yaml file

```yaml
# too.local.yaml
main:
    jobs:
    - run: rails server
    - run: npm start-webpack
```

then

```sh
% too ./too.local.yaml
```

## Including env files

You can merge `KEY=value` env files into the environment with `include.env_files`.
Paths are resolved from the current working directory.

```yaml
# too.local.yaml
include:
  env_files:
  - ./example/secrets.env   # KEY=value lines, merged into the environment
main:
  jobs:
  - run: echo $API_TOKEN
```

`env_files` is the only supported include form; the listed files are read as
`KEY=value` pairs (not as nested too-files). See `example/too.local.yaml`.

# Install

```sh
% npm install too
```
