// This code was submitted and written by Thomas Meitz (gwan at jproxx dot com)

// You have to install following packages on Debian to run this example:
//    apt-get install gobjc gnustep gnustep-make gnustep-common gnustep-devel
//
// Then you have to create the following links (with sudo or as root)
//    ln -s /usr/include/GNUstep/Foundation /usr/include/Foundation
//    ln -s /usr/include/GNUstep/GNUstepBase /usr/include/GNUstepBase
//    ln -s /usr/include/GNUstep/ObjectiveC2 /usr/include/ObjectiveC2
// ----------------------------------------------------------------------------
// imported functions:
//   get_reply(): get a pointer on the 'reply' dynamic buffer from the server
//    xbuf_cat(): like strcat(), but it works in the specified dynamic buffer
