+Currently the following languages are supported. First column corresponds to the
+standard debugging string while the second to the case of debugging for a
+specific variable.

+```c++
+// Debug String
+std::cout << "[a.c:4] DEBUGGING STRING ==> " << 0 << std::endl;
+
+// Debug Variable
+std::cout << "[a.c:4] a_variable: " << a_variable << std::endl;
