What is Octopi?

Octopi is a GUI package manager built on QT that makes using both of the Arch/Manjaro prime Terminal package managers - pacman & yaourt - simple point & click operations.

Octopi is capable of handling system updates & the installation of individual packages from both the official repositories & from the AUR. It can search for files using its search field, & be told whether to use the official repos or AUR or both.

Octopi uses a panel applet notifier (the octopi logo) which will turn red when there is a system update available.

Double clicking on the panel applet at any time will open octopi on your desktop.
