gentoo is a file manager written from scratch in pure C. It uses the GTK3
toolkit for all of its interface needs. gentoo provides 100% GUI
configurability; no need to edit config files by hand and re-start the
program. gentoo supports identifying the type of various files (using
extension, regular expressions, and/or the 'file' command), and can display
files of different types with different colors and icons. gentoo borrows
some of its look and feel from the classic Amiga file manager
"Directory OPUS"(TM) (written by Jonathan Potter).
