+ ******************************************************************************
+ *
+ * GnuCash relies on the GConf daemon to store and retrieve its internal
+ * configuration. That daemon implements a Windows-like, system-wide registry,
+ * which is very hard to support on NixOS because the concept is inherently
+ * impure. To register GnuCash's configuration schemas with GConf, you have to
+ * add ${gnucash}/etc/gconf/gconf.xml.defaults to GConf's search path, i.e. by
+ * adding the line
+ *
+ *   xml:readonly:$(HOME)/.nix-profile/etc/gconf/gconf.xml.defaults/
+ *
+ * to ~/.gconf.path in your user's home directory. Furthermore, the line
+ *
+ *   services.dbus.packages = [ pkgs.gnome.GConf ];
+ *
+ * must be added to /etc/nixos/configuration.nix to make sure the DBus daemon
+ * knows about GConf and starts it automatically whenever a program (such as
+ * GnuCash) needs it.
