RCSSmin is a CSS minifier. The implementation is based on the semantics of the YUI compressor, but aiming for speed instead of maximum compression so that it can be used at runtime rather than during a preprocessing step. rCSSmin does syntactical compression only (removing spaces, comments, and possibly semicolons). It does not provide semantic compression (like removing empty blocks, collapsing redundant properties etc). It does, however, support various CSS hacks (by keeping them working as intended).
ratproxy is a semi-automated, largely passive Web application security audit tool optimized for accurate and sensitive detection, and automatic annotation, of potential problems and security-relevant design patterns based on the observation of existing, user-initiated traffic in complex Web 2.0 environments.
RenderSnake is a Java libary for creating components and pages that produce HTML using only Java. Its purpose is to support the creation of Web applications that are more maintainable, allow for easier reuse, have testable UI components, and produce compact HTML in an efficient way.
Rerun is a lightweight tool-building framework useful to those implementing management procedure with shell scripts. It will help you organize your implementation into well-defined modular interfaces. Collections of management modules can be archived and delivered as a single executable to facilitate team handoffs. Using the "stubbs" module, rerun will even facilitate unit tests. When users execute rerun module commands, rerun can record execution data into log files which can later be replayed.
