+g:gutentags_resolve_symlinks
+                        When set to 1, Gutentags will resolve any symlinks in
+                        the current buffer's path in order to find the project
+                        it belongs to. This is what you want if you're editing
+                        a symlink located outside of the project, and it
+                        points to a file inside the project. However, this is
+                        maybe not what you want if the symlink itself is
