CrossVC 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 CrossVC XXL GUI aims for the unexperienced users and also complies with the requirements of professional users. CrossVC XXL 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, CrossVC 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. Allmost 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. CrossVC XXL can be fine-tuned to the project requirements, meaning size and performance. An internal ChangeSet viewer is included.Limitations:
