LXR Cross Referencer
LXR Cross Referencer, usually known as LXR, is a general-purpose source code indexer and cross-referencer for code comprehension that provides web-based browsing of source code, with links to the definition and usage of any identifier. == History == LXR was born from a need for a tool to keep a synthetic eye on the Linux kernel during its development (whence its original name: LXR stood for "Linux Cross-Referencer").
