STYLE

@@ -0,0 +1,7 @@
+If you intend to patch and contribute awesome, please respect the following coding style:
+- Use 4 space tabs instead of tabs;
+- Place braces alone on new lines;
+- Do not put very long line, split them;
+- Be clear in what you do.
+
+A vim modeline is set in each file to respect this.
