+/* Purpose
+ *
+ * 1. Accept a TCP connection on a custom port (ipv4 or ipv6).
+ *
+ * 2. Get commands on STDIN. Pass data on to the TCP stream.
+ * Get data from TCP stream and pass on to STDOUT.
+ *
+ * This program is made to perform all the socket/stream/connection stuff for
+ * the test suite's (perl) FTP server. Previously the perl code did all of
+ * this by its own, but I decided to let this program do the socket layer
+ * because of several things:
+ *
+ * o We want the perl code to work with rather old perl installations, thus
+ * we cannot use recent perl modules or features.
+ *
+ * o We want IPv6 support for systems that provide it, and doing optional IPv6
+ * support in perl seems if not impossible so at least awkward.
+ *
+ * o We want FTP-SSL support, which means that a connection that starts with
+ * plain sockets needs to be able to "go SSL" in the midst. This would also
+ * require some nasty perl stuff I'd rather avoid.
+ *
+ * (Source originally based on sws.c)
