"CDE is a tool that automatically packages up the Code, Data, and Environment involved in running any Linux command so that it can execute identically on another computer without any installation or configuration. The only requirement is that the other computer have the same hardware architecture (e.g., x86) and major kernel version (e.g., 2.6.X) as yours. CDE allows you to easily run programs without the dependency hell that inevitably occurs when attempting to install software or libraries. You can use CDE to allow your colleagues to reproduce and build upon your computational experiments, to quickly deploy prototype software to a compute cluster, and to submit executable bug reports."
