I discovered it while hunting down small apps for a sub 50 megs Knoppix/Debian business card size CD hack I am throwing together.
It is modeled after Amiga's Directory Opus. This is the first X based file manager that puts function over form. It works with directly with X, so dependencies are low, and it's very fast and light -- definitely a geek's file manager.
Yeah, pretty much. I got a relatively useful desktop into 50 megs. I am still working on it but I got ftp, ssh/scp, graphic browser, file manager, irc, Vi, standard X apps (like calculator), and busybox. -- working on email.
