// wininit.cpp - initialize windows desktop
/* wininit reads the [WinInit] section of WIN.INI, and launches
programs as listed, moving their windows as indicated.
WIN.INI format:
[WinInit]
win1=Show X Y Dx Dy D:\path\name1.exe [args]
win2=Show X Y Dx Dy D:\path\name2.exe [args]
[...]
win1 ... win63 = tags for windows (loaded in numerical order,
NOT in the order found in WIN.INI)
Show = ShowWindow value (1=normal, 2=minimized[=icon])
X,Y = upper left corner coordinates
Dx,Dy = width and height (in pixels)
wininit should be the ONLY program named in window's "run="
and "load=" lines. By putting wininit.exe in the "load=" line,
the program manager window will appear normally; by putting
wininit.exe in the "run=" line, the program manager will appear
as an icon.
This program has no windows - it merely launches the proper
programs and exits.
