   9 # This program examines the contents of the DOS filesystems and
  10 # attempts to generate a sensible wine.conf file.  This is output
  11 # to STDOUT.
  12 # It reads /etc/FSTAB to find mounting locations of the hard disk drives
  13 # It uses the correct algorithm for ordering DOS drives, with the
  14 # exception of the case of multiple drive controller types, where I don't
  15 # know what DOS's algorithm is.
  16 # It uses find to find all of the win.ini files on any DOS partition
  17 # and sorts them by age to guess which is part of the active Windows
  18 # installation.
  19 # It reads the autoexec.bat file (if found) and records all variable
  20 # settings.   There are some inaccuracies in its determination.
  21 # First, while variables are interpolated properly, no control
  22 # structures are supported so calls and execs to other batch files are
  23 # ignored, and all variable settings take effect regardless of whether
  24 # they would in DOS (i,e., both if and else clauses are read).
  25 # This is used to determine the path and temp directories.  Duplicate
  26 # path directories and path directories that don't exist are thrown
  27 # out.
  28 # On failing to find C:\AUTOEXEC.BAT, wineconf finds all executables
  29 # in the windows directory and subdirectories, and generates an
  30 # optimized path statement encompassing all the executables.
  31 # Then it also looks for \TEMP and \TMP on all drives taking the first
  32 # one it finds.
  33 # wineconf doesn't support floppy drives, network drives, printers,
  34 # and serial device configuration is hardcoded and not configured for
  35 # the machine it runs on.  Similarly, spy parameters are hard coded.
  36
  37 # It would make sense to incorporate much of the heuristic code in
  38 # this program into a library to be shared with a dosemu configuration
  39 # program, because it seems that at least some of the same stuff will
  40 # be wanted.  The program needs to be cleaned up still.  A better tmp
  41 # search algorithm could be written.  A fast option is planned.  Less
  42 # Linux-dependence is desired.  Should look for devices independent
  43 # of /etc/fstab; then sanity checks on /etc/fstab can be performed.
