/**
 * This code uses the ClientTest and and information provided by
 * the backends in their RegisterSyncSourceTest instances to test
 * real synchronization with a server.
 *
 * Configuration is done by environment variables which indicate which
 * part below the root node "client-test" of the the configuration tree to use;
 * beyond that everything needed for synchronization is read from the
 * configuration tree.
 *
 * - CLIENT_TEST_SERVER = maps to name of root node in configuration tree
 * - CLIENT_TEST_EVOLUTION_PREFIX = a common "evolutionsource" prefix for *all*
 *                                  sources; the source name followed by "_[12]"
 *                                  is appended to get unique names
 * - CLIENT_TEST_EVOLUTION_USER = sets the "evolutionuser" property of all sources
 * - CLIENT_TEST_EVOLUTION_PASSWORD = sets the "evolutionpassword" property of all sources
 * - CLIENT_TEST_SOURCES = comma separated list of active sources,
 *                         names as selected in their RegisterSyncSourceTest
 *                         instances
 * - CLIENT_TEST_DELAY = number of seconds to sleep between syncs, required
 *                       by some servers
 * - CLIENT_TEST_LOG = logfile name of a server, can be empty:
 *                     if given, then the content of that file will be
 *                     copied and stored together with the client log
 *                     (only works on Unix)
 * - CLIENT_TEST_NUM_ITEMS = numbers of contacts/events/... to use during
 *                           local and sync tests which create artificial
 *                           items
 *
 * The CLIENT_TEST_SERVER also has another meaning: it is used as hint
 * by the synccompare.pl script and causes it to automatically ignore
 * known, acceptable data modifications caused by sending an item to
 * a server and back again. Currently the script recognizes "funambol",
 * "scheduleworld", "synthesis" and "egroupware" as special server
 * names.
