BioGrids includes a software environment called the capsule environment.
This software programmatically creates custom environments for every BioGrids application at the time of execution.
Configurations, paths, dependencies and other items needed by the application are created and or set at execution time. The application is then run in this environment. When the application exits the environment is cleaned up and removed.
The Capsule Environment approach enables a much faster execution environment for users with minimal interference to the users own default shell environment.
