 // --- How to use these 2 functions :
 $outputDirectory = "output";
 $inputDirectory 	= "input";
 // 1°) Clean output directory :
 echo "<BR><b>Clean output directory ".$outputDirectory." :</b>";
 cleanDirectory($outputDirectory);
 // 2°) Copy documents from input directory to output directory :
 echo "<BR><b>Copy documents :</b>";
 copyDocuments($inputDirectory, $outputDirectory);
