There is a single no-parameter generator, that clones the neutron's project into the current directory:
Apart from cloning the neutron repository, two directories,
dist, are created . Neutron expects source files to be in the former, and the transpiled/compiled/etc. files are stored in the latter directory.
The only error that might happen, is that you try to bootstrap neutron in a non-empty directory. This is going to fail, since git only clones in empty directories.
