  20  * FIXME: Rather non-functional functions for now.
  21  *
  22  * See:

  24  * http://willemer.de/informatik/windows/inf_info.htm (German)

  29  * http://support.microsoft.com/support/kb/articles/q194/6/40.asp
  30  *
  31  * Stuff tested with:
  32  * - rs405deu.exe (German Acroread 4.05 setup)
  33  * - ie5setup.exe
  34  * - Netmeeting
  35  *
  36  * FIXME:
  37  * - string handling is... weird ;) (buflen etc.)
  38  * - memory leaks ?
  39  * - separate that mess (but probably only when it's done completely)
  40  *
  41  * SETUPX consists of several parts with the following acronyms/prefixes:
  42  * Di   device installer (devinst.c ?)
  43  * Gen  generic installer (geninst.c ?)
  44  * Ip   .INF parsing (infparse.c)
  45  * LDD  logical device descriptor (ldd.c ?)
  46  * LDID logical device ID
  47  * SU   setup (setup.c ?)
  48  * Tp   text processing (textproc.c ?)
  49  * Vcp  virtual copy module (vcp.c ?)
  50  * ...
  51  *
  52  * The SETUPX DLL is NOT thread-safe. That's why many installers urge you to
  53  * "close all open applications".
  54  * All in all the design of it seems to be a bit weak.
  55  * Not sure whether my implementation of it is better, though ;-)
