+/*
+ * This code sets up multiple easy handles that transfer a single file from
+ * the same URL, in a serial manner after each other. Due to the connection
+ * sharing within the multi handle all transfers are performed on the same
+ * persistent connection.
+ *
+ * This source code is used for lib526, lib527 and lib532 with only #ifdefs
+ * controlling the small differences.
+ *
+ * - lib526 closes all easy handles after
+ *   they all have transferred the file over the single connection
+ * - lib527 closes each easy handle after each single transfer.
+ * - lib532 uses only a single easy handle that is removed, reset and then
+ *   re-added for each transfer
+ *
+ * Test case 526, 527 and 532 use FTP, while test 528 uses the lib526 tool but
+ * with HTTP.
