Shebang line on Linux for pipelines does not work

Just an FYI, this does not work in Linux as the shebang line will try to execute 
`"jip -p"` not `"jip"` `"-p"`

The documentation references this quite often

```
#!/usr/bin/env jip -p
```

Not a huge deal as you just have to just create a `#%begin pipeline` block and it seems to work the same
