+# This is a server designed for the curl test suite.
+#
+# In December 2009 we started remaking the server to support more protocols
+# that are similar in spirit. Like POP3, IMAP and SMTP in addition to the FTP
+# it already supported since a long time. Note that it still only supports one
+# protocol per invoke. You need to start multiple servers to support multiple
+# protocols simultaneously.
+#
+# It is meant to exercise curl, it is not meant to be a fully working
+# or even very standard compliant server.
+#
+# You may optionally specify port on the command line, otherwise it'll
+# default to port 8921.
+#
+# All socket/network/TCP related stuff is done by the 'sockfilt' program.
