Distro is chosen through -m / --mode. Current supported options are arch (which graphs your installed packages),arch-repo (which graphs every official package in the repositories), debian and redhat. Currently there are no full repository loaders for debian or redhat. The git version has ipkg support. This is commonly used for embedded Debian, and needed only two small tweaks. It will make it into the tarball once I can find my WRT54G and adequately test it.
