+$! This command file compiles and creates the "[.xxx.EXE.SSL]LIBSSL.OLB"
+$! library for OpenSSL. The "xxx" denotes the machine architecture of
+$! ALPHA, IA64 or VAX.
+$!
+$! It is written to detect what type of machine you are compiling on
+$! (i.e. ALPHA or VAX) and which "C" compiler you have (i.e. VAXC, DECC
+$! or GNU C) or you can specify which compiler to use.
+$!
+$! Specify the following as P1 to build just that part or ALL to just
+$! build everything.
+$!
+$! LIBRARY To just compile the [.xxx.EXE.SSL]LIBSSL.OLB Library.
+$! SSL_TASK To just compile the [.xxx.EXE.SSL]SSL_TASK.EXE
+$!
+$! Specify DEBUG or NODEBUG as P2 to compile with or without debugger
+$! information.
+$!
+$! Specify which compiler at P3 to try to compile under.
+$!
+$! VAXC For VAX C.
+$! DECC For DEC C.
+$! GNUC For GNU C.
+$!
+$! If you don't specify a compiler, it will try to determine which
+$! "C" compiler to use.
+$!
+$! P4, if defined, sets a TCP/IP library to use, through one of the following
+$! keywords:
+$!
+$! UCX for UCX
+$! TCPIP for TCPIP (post UCX)
+$! SOCKETSHR for SOCKETSHR+NETLIB
+$!
+$! P5, if defined, sets a compiler thread NOT needed on OpenVMS 7.1 (and up)

+ * DECnet object for servicing SSL. We accept the inbound and speak a
+ * simple protocol for multiplexing the 2 data streams (application and
+ * ssl data) over this logical link.
+ *
+ * Logical names:
+ * SSL_CIPHER Defines a list of cipher specifications the server
+ * will support in order of preference.
+ * SSL_SERVER_CERTIFICATE
+ * Points to PEM (privacy enhanced mail) file that
+ * contains the server certificate and private password.
+ * SYS$NET Logical created by netserver.exe as hook for completing
+ * DECnet logical link.
+ *
+ * Each NSP message sent over the DECnet link has the following structure:
+ * struct rpc_msg {
+ * char channel;
+ * char function;
+ * short length;
+ * char data[MAX_DATA];
+ * } msg;
+ *
+ * The channel field designates the virtual data stream this message applies
+ * to and is one of:
+ * A - Application data (payload).
+ * R - Remote client connection that initiated the SSL connection. Encrypted
+ * data is sent over this connection.
+ * G - General data, reserved for future use.
+ *
+ * The data streams are half-duplex read/write and have following functions:
+ * G - Get, requests that up to msg.length bytes of data be returned. The
+ * data is returned in the next 'C' function response that matches the
+ * requesting channel.
+ * P - Put, requests that the first msg.length bytes of msg.data be appended
+ * to the designated stream.
+ * C - Confirms a get or put. Every get and put will get a confirm response,
+ * you cannot initiate another function on a channel until the previous
+ * operation has been confirmed.
+ *
+ * The 2 channels may interleave their operations, for example:
+ * Server msg Client msg
+ * A, Get, 4092 ---->

+ - The servername is acknowledged if it is new for a session or when
+ it is identical to a previously used for the same session.
+ Applications can control the behaviour. They can at any time
+ set a 'desirable' servername for a new SSL object. This can be the
+ case for example with HTTPS when a Host: header field is received and
+ a renegotiation is requested. In this case, a possible servername
+ presented in the new client hello is only acknowledged if it matches
+ the value of the Host: field.
+ - Applications must use SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION
+ if they provide for changing an explicit servername context for the session,
+ i.e. when the session has been established with a servername extension.
+ - On session reconnect, the servername extension may be absent.
