+  Note that this version of the extension still has some nix specific issues
+  which could not be fixed merely by patching (inside a C# dll).
+
+  In particular, the debugger requires either gnome-terminal or xterm. However
+  instead of looking for the terminal executable in `PATH`, for any linux platform
+  the dll uses an hardcoded path to one of these.
+
+  So, in order for debugging to work properly, you merely need to create symlinks
+  to one of these terminals at the appropriate location.
+
+  The good news is the the utility library is open source and with some effort
+  we could build a patched version ourselves. See:
+
+  <https://github.com/Microsoft/MIEngine/blob/2885386dc7f35e0f1e44827269341e786361f28e/src/MICore/TerminalLauncher.cs#L156>
+
+  Also, the extension should eventually no longer require an external terminal. See:
+
+  <https://github.com/Microsoft/vscode-cpptools/issues/35>
+
+  Once the symbolic link temporary solution taken, everything shoud run smootly.
