$!  This command file compiles and creates the various engines in form
$!  of shared images.  They are placed in [.xxx.EXE.ENGINES], where "xxx"
$!  is ALPHA, IA64 or VAX, depending on your hardware.
$!
$!  P1	if this is ENGINES or ALL, the engines will build, otherwise not.
$!
$!  P2	DEBUG or NODEBUG to compile with or without debugger information.
$!
$!  P3  VAXC		for VAX C
$!	DECC		for DEC C
$!	GNUC		for GNU C (untested)
$!
$!  P4	if defined, sets the TCP/IP libraries to use.  UCX or TCPIP is
$!	used by default since most other implementations come with a
$!	compatibility library.  The value must be one of the following:
$!
$!	UCX		for UCX
$!	SOCKETSHR	for SOCKETSHR+NETLIB
$!	TCPIP		for TCPIP (post UCX)
$!
$!  P5	if defined, tells the compiler not to use special threads.
$!
$!  P6	if defined, denotes which engines to build.  If not defined,
$!	all available engines are built.
$!
$!  P7, 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).
$!
$!  P8, 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).
