LinCVS XXL is a platform independent graphical interface for the cvs command line client. It covers the cvs instruction set, and allows intuitive and graphical handling of cvs projects. The LinCVS XXL GUI aims towards unexperienced users, yet complies with the requirements of sophisticated and professional users. It plugs into the native look and feel, and is distributed with all required tools, so a simple unzip installs it all. In contrast to other cvs clients, LinCVS XXL is a platform independent solution that supports multiple projects at once, allows repository inspection without previous checkout and has fine-grained internal merge/preview features. Almost all dialogs are non-modal, so for example inspecting the projects is possible while writing a commit message. File states are continuously monitored, and recognize external cvs actions without user interaction. LinCVS XXL can be fine-tuned to the project requirements, meaning size and performance. An internal ChangeSet viewer is included.
