...Installation: Move (don't copy) the .hpkg file into /boot/home/config/packages on any Haiku installation with Package Management enabled. If your Haiku installation is quite up-to-date, you should be able to double-click the .hpkg and have it load into HaikuDepot, ready for installation.
The source files will be found in /boot/home/config/data/src after installation, in Yabadabbadoo format.
