## Description

OpenGrok is a Java-based source code search engine and indexer designed to process large source trees and binaries into a searchable index. It functions as a version control browser, allowing for the exploration and searching of revision histories integrated with version control systems.

The system provides symbol-based cross-referencing to link code definitions and usages, enabling navigation across a codebase. It utilizes an inverted-index search engine to perform full-text retrieval of source code.

The application supports periodic source synchronization and reindexing to keep local data current. Deployment is supported through container images to maintain consistent environments across hosting platforms.
