luet-portage-converter at the moment has two different backend to generate luet specs:

• qdepends: based on Gentoo qdepends tool. This backend requires that the packages must be installed on the system where is executed luet-portage-converter. It doesn't work well with overlays. This backend will be soon set as deprecated.

• reposcan: based on Funtoo reposcan generated files. It uses the JSON files generated and doesn't require that the packages must be installed 🍾 and it support Gentoo Overlay and Funtoo Kits.
