+ * 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 _and_ lib527 with only #ifdefs
+ * controlling the small differences. lib526 closes all easy handles after
+ * they all have transfered the file over the single connection, while lib527
+ * closes each easy handle after each single transfer. 526 and 527 use FTP,
+ * while 528 uses the lib526 tool but use HTTP.
