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

28 * http://www.rdrop.com/~cary/html/inf_faq.html
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 ;-)
