The record

Purpose: LXR indexes and cross-references source code for web browsing, linking identifiers to their definitions and uses.
Project scope: The project says it can cross-reference projects beyond the Linux kernel.
Browser output: LXR produces regular HTML that can be viewed in available web browsers.
Server requirement: The project says any web server with CGI-script capability should work.
Installation: The installation guide instructs users to install LXR source, configure a database, populate it with source-tree data, and configure a web server.
Database choices: The configuration guide lists MySQL, Oracle, PostgreSQL, and SQLite as database choices.
Search: LXR 2.3 adds full-text search for source management repositories except CVS and BitKeeper, if users accept checking out repository sources.
Version control: The installation configuration lists files, CVS, Git, Subversion, and BitKeeper as source-tree storage options.
Security: The feature log says release 2.3 added protection against a vulnerability that allowed arbitrary command execution.
Database access: The feature log says browsing access to the database is read-only, with write access reserved for genxref.
Parser limits: The limitations page says language parsers are not compiler-grade and lexically extract character sequences that look like identifiers.
Support: The project directs users to its forum and trackers to contact developers and report issues.
Release location: The official site says new releases are being migrated to Codeberg and will only be posted there.
Intended use: The project describes LXR as useful for monitoring a project during development and studying source code from scratch.
