  20 # NOTES:
  21 #
  22 # This program examines the contents of the DOS filesystems and
  23 # attempts to generate a sensible wine.conf file.  This is output
  24 # to STDOUT.
  25 # It reads /etc/fstab to find mounting locations of the hard disk drives
  26 # It uses the correct algorithm for ordering DOS drives, with the
  27 # exception of the case of multiple drive controller types, where I don't
  28 # know what DOS's algorithm is.
  29 # It uses find to find all of the win.ini files on any DOS partition
  30 # and sorts them by age to guess which is part of the active Windows
  31 # installation.
  32 # It reads the autoexec.bat file (if found) and records all variable
  33 # settings.   There are some inaccuracies in its determination.
  34 # First, while variables are interpolated properly, no control
  35 # structures are supported so calls and execs to other batch files are
  36 # ignored, and all variable settings take effect regardless of whether
  37 # they would in DOS (i,e., both if and else clauses are read).
  38 # This is used to determine the path and temp directories.  Duplicate
  39 # path directories and path directories that don't exist are thrown
  40 # out.
  41 # On failing to find C:\AUTOEXEC.BAT, wineconf finds all executables
  42 # in the windows directory and subdirectories, and generates an
  43 # optimized path statement encompassing all the executables.
  44 # Then it also looks for \TEMP and \TMP on all drives taking the first
  45 # one it finds.
  46 # wineconf doesn't support floppy drives, network drives, printers,
  47 # and serial device configuration is hardcoded and not configured for
  48 # the machine it runs on.  Similarly, spy parameters are hard coded.
  49
  50 # It would make sense to incorporate much of the heuristic code in
  51 # this program into a library to be shared with a dosemu configuration
  52 # program, because it seems that at least some of the same stuff will
  53 # be wanted.  The program needs to be cleaned up still.  A better tmp
  54 # search algorithm could be written.  A fast option is planned.  Less
  55 # Linux-dependence is desired.  Should look for devices independent
  56 # of /etc/fstab; then sanity checks on /etc/fstab can be performed.
