“CDE is a tool that automatically packages up the Code,
Data, and Environment involved in running any set of Linux commands
so that they 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.“CDE is easy to use: Simply prepend any Linux command (or series
of commands) with cde, and CDE will execute that command, monitor
its actions, and automatically copy all files it accesses (e.g.,
executables, dynamically linked/loaded libraries, plug-ins,
scripts, configuration/data files) into a package within your
current working directory. Now you can transfer the package to
another computer and run that same command without installing
anything. In short, if you can run a set of Linux commands on your
computer, then CDE enables others to run it on theirs.”
