"List of strings containing commands to start TLS stream to a host.
Each entry in the list is tried until a connection is successful.
-%h is replaced with server hostname, %p with port to connect to.
+%h is replaced with the server hostname, %p with the port to
+connect to, and %t with a file name containing trusted certificates.
The program should read input on stdin and write output to stdout.
