   Configuration script for the fxengine library.
   Usage: $0 [options...]


Specified target :

  --fxcg50

  --fx9680g

If you don't send any option, fx9860g is set as default
* Note fxcg50 is not really supported now, but maybe someday it would happen !



Optional dependencies :

  --libprof
     By default, profiling is disabled, tht means you will not have access to fps. :(
     This option enables fps count, but you need to have libprof (by Lephenixnoir) installed

  --liblog
     If you want more advanced debug options, you can add this to add a virtual stream used for
     logging debug informations
     You need tou have liblog (by me) installed
