$!  This command files compiles and creates the
$!  "[.xxx.EXE.CRYPTO.DES]LIBDES.OLB" library.  The "xxx" denotes the machine
$!  architecture of AXP or VAX.
$!
$!  It was re-written to try to determine which "C" compiler to try to use
$!  or the user can specify a compiler in P3.
$!
$!  Specify one of the following to build just that part, specify "ALL" to
$!  just build everything.
$!
$!         ALL       To Just Build "Everything".
$!         LIBRARY   To Just Build The [.xxx.EXE.CRYPTO.DES]LIBDES.OLB Library.
$!         DESTEST   To Just Build The [.xxx.EXE.CRYPTO.DES]DESTEST.EXE Program.
$!         SPEED     To Just Build The [.xxx.EXE.CRYPTO.DES]SPEED.EXE Program.
$!         RPW       To Just Build The [.xxx.EXE.CRYPTO.DES]RPW.EXE Program.
$!         DES       To Just Build The [.xxx.EXE.CRYPTO.DES]DES.EXE Program.
$!         DES_OPTS  To Just Build The [.xxx.EXE.CRYPTO.DES]DES_OPTS.EXE Program.
$!
$!  Specify either DEBUG or NODEBUG as P2 to compile with or without
$!  debugging 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 speficy a compiler, it will try to determine which
$!  "C" compiler to try to use.
$!
$!  P4, if defined, sets a compiler thread NOT needed on OpenVMS 7.1 (and up)
