SUMMARY = "CRIU"
DESCRIPTION = "Checkpoint/Restore In Userspace, or CRIU, is a software tool for \
Linux operating system. Using this tool, you can freeze a running application \
(or part of it) and checkpoint it to a hard drive as a collection of files. \
You can then use the files to restore and run the application from the point \
it was frozen at. The distinctive feature of the CRIU project is that it is \
mainly implemented in user space"
