Heretix was a linux distribution which aimed at using Ruby instead of
traditional sh/dash scripts or other GNU tools.

I don't know how far along the package management was, but that was a
goal along with a rewrite of init scripts.

The package management was to be inspired by GoboLinux, with packages in
individual subdirectories and with automated symlink maintenance.

The project died in early 2007.  If there is enough interest, I could
dig up my contact information for the authors.
