   2  * SetupX .inf file parsing functions

   4  * FIXME:
   5  * - return values ???
   6  * - this should be reimplemented at some point to have its own
   7  *   file parsing instead of using profile functions,
   8  *   as some SETUPX exports probably demand that
   9  *   (IpSaveRestorePosition, IpFindNextMatchLine, ...).
