My build process builds the target files in `build_dir/bootfs/`.
I use:
```
artifact:
- paths: build_dir/bootfs/*
```
The files in `artifact.zip` will extract to `../build_dir/bootfs/`.
Is it possible to specify that the path leading up to the files being zipped is not to be included in the zipfile so that when I unzip the archive the files that were originally in `build_dir/bootfs` end up in the current directory?
