****************************** DSS HowTo **************************************

  To link the DSS lib-file ALL symbols (functions) that are stated as
  imported by the DSS in the "dss_interface.hh"-file MUST be implemented
  EXACTLY as declared. A typical linking error if one is missing is
  "reference to symbol: XXX not found in ..."

 For use with supplied examples and utilities configure with correct flags.
 The examples can be compiled in their respective subtrees if not all are wanted,
 just enter the subtree and type "make".
 configurations:
 * "--enable-opt"            to optimize for either (flag): (d) debug, (std) normal.

 * "--enable-dss-examples"   to generate Makefiles for examples AND place in root "install"
                             !! IF supplied with the first letter of the wanted example, ONLY 
                             that example will be created !!

 * "--enable-msgn-examples"  to generate Makefiles for messaging examples AND place in root "install"
                             !! IF supplied with the first letter of the wanted example, ONLY that
                             will be created !!

 * "--enable-modules-static" Configure static or dynamic linking, i.e. yes = static and no = dynamic

 * "--enable-utils"          to generate Makefile for utilities AND place in root "install", options
                             are: dss (default with empty selection), messaging (i.e. a reference 
                             IO_Factory and CSC), ...
                             This option will default to dss, which includes messaging, if any dss
                             example is enabled and default to messaging if such examples are selected

 * "--enable-warnings"       This flag is ALLWAYS TURNED ON. to disable warnings, set to "no". If set
			     to "error" warnings are also treated as errors

 * "--enable-profiling"	     Embeds gprof information into the library for performance evaluation

 * "--enable-build"          Configure the build directory for compilation of: dss (default), messaging,
                             ...

 If compiling on your own there are some flags to be aware of:
 * "DEBUG_CHECK", adds extra safety during execution by introducing our own asserts, which basicly
                checks for conditions that should be fulfilled and if not calls the GL_error routine.
 * "DSS_LOG",   add multi-leveled verbose printouts during execution. Depending on the level, different
                types of status messages are printed. This tool might be useful during implementation
                of a MAP layer. for more info check out the dssBase.hh in the source directory.
 * "INTERFACE", enables space-saving gcc pragma directives (for instance during debug compilation)
 * "WIN32",     Signal that we're in the windows environment and should use such headers
