Right now it is dead slow but help is on the way. However, ClearCase permissions are tied to the OS. Read honest and unbiased product reviews from our users. They follow a model very similar to the Unix filesystem. It manages multiple variants of evolving software systems, tracks which versions were used in software builds, performs builds of individual programs or entire releases according to user-defined version specifications, and enforces site-specific development policies. One that scales. Brad has more than 20 years of experience in high-tech companies focused on optimizing development pipelines.
