* Mandos client - get and decrypt data from a Mandos server
7
* End user applications should *not* use this API and should use
8
* the D-Bus or C APIs, please see
9
* client-browse-services.c and glib-integration.c
11
* I repeat, you probably do *not* want to use this example.

* This program is partly derived from an example program for an Avahi
6
* service browser, downloaded from

* <http://avahi.org/browser/examples/core-browse-services.c>. This
8
* includes the following functions: "resolve_callback",
