$!
$!  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)
$!
$!  P6, if defined, specifies the C pointer size.  Ignored on VAX.
$!      ("64=ARGV" gives more efficient code with HP C V7.3 or newer.)
$!      Supported values are:
$!
$!      ""       Compile with default (/NOPOINTER_SIZE)
$!      32       Compile with /POINTER_SIZE=32 (SHORT)
$!      64       Compile with /POINTER_SIZE=64[=ARGV] (LONG[=ARGV])
$!               (Automatically select ARGV if compiler supports it.)
$!      64=      Compile with /POINTER_SIZE=64 (LONG).
$!      64=ARGV  Compile with /POINTER_SIZE=64=ARGV (LONG=ARGV).
$!
$!  P7, if defined, specifies a directory where ZLIB files (zlib.h,
$!  libz.olb) may be found.  Optionally, a non-default object library
$!  name may be included ("dev:[dir]libz_64.olb", for example).
