For more exact detail, look in the copyright statements in individual
files.

Finally, ArX includes a few libraries written by others: Loki
(src/loki), Boost (src/boost), and a SHA hash function
(src/arx/libarx/sha256/).  Credits for those projects can be
found in their individual directories.

In addition, ArX uses other utilities from the Free Software
Foundation (diff, patch, tar) and the Gnome Project (gnome-vfs).
