/**
* @file test_gns_vpn.c
* @brief testcase for accessing VPN services via GNS
* @author Martin Schanzenbach
+ * @author Christian Grothoff
+ *
+ * This test requires libcurl/libgnurl *with* support for C-ARES.
+ * This is NOT the default on most platforms, which means the test
+ * will be skipped in many cases. Compile libcurl/libgnurl with
+ * "--enable-ares" to get this test to pass.
+ *
+ * Furthermore, the test relies on gnunet-dns2gns being able to bind
+ * to port 53. This means that 'setcap' has to have worked during
+ * 'make install'. If this failed, but everything else is OK, the
+ * test may FAIL hard even though it is just an installation issue (we
+ * cannot conveniently test for the setcap to have worked). However,
+ * you should get a warning that gnunet-dns2gns failed to 'bind'.
