Many C++ extractors exist that produce syntax trees, call graphs, and metrics from C++ code, yet few offer integrated querying, navigation, and visualization of source-code-level facts to the end-user We present an interactive reverse engineering environment which supports reverse-engineering tasks on C/C++ code, e.g. set up the extraction process, apply user-written queries on the extracted facts, and visualize query results, much like classical forward-engineering IDEs do. We illustrate our environment with several examples of reverse-engineering analyses.</p
