+REM Generation of a DLL under Microsoft Visual C/C++, providing the C functions
+REM of the FLINT/C package. Deployment of the DLL is accomplished by linking
+REM the import library flint.lib to an application. The file flint.def contains
+REM a list of the exported symbols.
+
+REM On loading the DLL the run time system automatically calls the function
+REM DllMain(). This function is responsible for initializing the randomnumber
+REM generators and the bank of CLINT registers. Any application is free to
+REM initialize the random number generators on their own with any suitable value
+REM (in any case this is recommended for security-critical applications).
+REM A reinitialization of the bank of registers by an application is without 
+REM effect, though the application has to free the allocated registers in its
+REM own responsibility.
