1OpenVMS port of Xscreensavser version 2.10     October 1997
2==========================================
3
4Xscreensaver distribution can be found in 3 subdirectories:
5
6[.DRIVER]   The Xscreensaver and Xscreensaver-command programs.
7[.HACKS]    Graphic demos ,can be run either through the xscreensaver program
8            or standalone.
9[.UTILS]    A small libraries of various utilities.
10
11This port has been tested with  VAX VMS 6.1 (compiled with DEC 5 5.0 and
12Motif 1.2) and AXP VMS 6.2 (compiled with DEC C 5.0 and Motif 1.2-4).
13
14To rebuild, you need to rebuild [.UTILS] directory first and create the
15object library (look at the end of COMPILE*.COM procedure).
16
17You can now build the [.HACKS] directory and the [.DRIVER] directory.
18
19A one-step build is now available via the MAKEVMS.COM script.
20
21WARNING : before building [.HACKS], you may need to correct some of the
22DECwindows bitmap files. Some files are bogus !! (they have a long line of
23null chars  at the end). These files are under
24SYS$COMMON:[DECW$INCLUDE.BITMAPS] directory:
25
26STIPPLE.XBM
27HLINES2.XBM
28LIGHT_GRAY.XBM
29ROOT_WEAVES.XBM
30VLINES2.XBM
31
32These files are all used by Greynetic demo.
33
34Nota: link procedure automagically select appropriate X and Motif Libraries
35(X11R4/Motif 1.1 - X11R5/Motif 1.2).
36
37The SETUP.COM procedure gives you a definition of all DCL foreign command
38symbols needed to run Xscreensaver and all the graphic hacks. You need to
39modify this procedure if you install these programs in another directory tree.
40
41You can easily add new graphic demos without recompiling Xscreensaver. You just
42need to add them in resource file XSCREENSAVER.DAT. This file (originally
43present in [.DRIVER] directory ) can be installed under your SYS$LOGIN
44directory for a per-user customization basis. You can also install it under
45the system-wide user resource directory SYS$COMMON:[DECW$DEFAULT.USER]
46(with (W:RE) protections). The new graphics hack must be run in root-window
47mode to be accepted by Xscreensaver.
48
49The graphic demos are spawn into subprocess created by the system() call (in
50the Unix version the execvp() call is used).
51
52The VMS passord checking programs were picked up in the Xlock distribution.
