dnl  Usage
dnl  =====
dnl  Just add HK_CLASSESTEST to your configure.in file
dnl  If you want to develop under KDE add HK_CLASSESTEST and HK_KDECLASSESTEST at the very end of your
dnl  configure.in, just before the AC_OUTPUT entry.
dnl  It is very important to that HK_KDECLASSESTEST stands after HK_CLASSESTEST
dnl  and all KDE specific entries.

  If you have installed the library in another directory than
  /usr/lib/hk_classes
  and the header files in : /usr/include/hk_classes
  use the configure paramaters:

  --with-hk_classes-dir=PATH      Path to the hk_classes directory
  --with-hk_classes-incdir=PATH   Path to the hk_classes header files
