$!
$! This procedure creates the SSL libraries of "[.xxx.EXE.CRYPTO]LIBCRYPTO.OLB"
$! "[.xxx.EXE.SSL]LIBSSL.OLB" and if specified "[.xxx.EXE.RSAREF]LIBRSAGLUE.OLB".
$! The "xxx" denotes the machine architecture of AXP or VAX.
$!
$! This procedures accepts two command line options listed below.
$!
$! Specify one of the following build options for P1.
$!
$!      ALL       Just build "everything".
$!      BUILDINF  Just build the "[.CRYPTO]BUILDINF.H" file.
$!      SOFTLINKS Just fix the Unix soft links.
$!      RSAREF    Just build the "[.xxx.EXE.RSAREF]LIBRSAGLUE.OLB" library.
$!      CRYPTO    Just build the "[.xxx.EXE.CRYPTO]LIBCRYPTO.OLB" library.
$!      SSL       Just build the "[.xxx.EXE.SSL]LIBSSL.OLB" library.
$!      SSL_TASK  Just build the "[.xxx.EXE.SSL]SSL_TASK.EXE" program.
$!      TEST      Just build the "[.xxx.EXE.TEST]" test programs for OpenSSL.
$!      APPS      Just build the "[.xxx.EXE.APPS]" application programs for OpenSSL.
$!
$!
$! Specify RSAREF as P2 to compile using the RSAREF Library.
$! If you specify NORSAREF, it will compile without using RSAREF.
$! (If in the United States, You Must Compile Using RSAREF).
$!
$! Note: The RSAREF libraries are NOT INCLUDED and you have to
$!       download it from "ftp://ftp.rsa.com/rsaref".  You have to
$!       get the ".tar-Z" file as the ".zip" file dosen't have the
$!       directory structure stored.  You have to extract the file
$!       into the [.RSAREF] directory as that is where the scripts
$!       will look for the files.
$!
$! Speficy DEBUG or NODEBUG as P3 to compile with or without debugging
$! information.
$!
$! Specify which compiler at P4 to try to compile under.
$!
$!	  VAXC	 For VAX C.
$!	  DECC	 For DEC C.
$!	  GNUC	 For GNU C.
$!	  LINK   To only link the programs from existing object files.
$!               (not yet implemented)
$!
$! If you don't speficy a compiler, it will try to determine which
$! "C" compiler to use.
$!
$!  P5, if defined, sets a TCP/IP library to use, through one of the following
$!  keywords:
$!
$!	UCX		for UCX or UCX emulation
$!	SOCKETSHR	for SOCKETSHR+NETLIB
$!
$! P6, if defined, sets a compiler thread NOT needed on OpenVMS 7.1 (and up)
$!
$!
$! Check Which Architecture We Are Using.
$!
$ IF (F$GETSYI("CPU").GE.128)
