rrr - rsync (rapidly,repeatedly) recent rubbish
rrr does not exist yet, try man File::Rsync::Mirror::Recent
This program does not exist yet. I am still musing about the interface, for now, please see the file HOWTO.mirrorcpan in the File::Rsync::Mirror::Recent distribution and follow the instructions there.
The usual blurb: rersyncrecent is a project to get speedy rsync operation on large trees over multiple hosts. It maintains a collection of files with metadata (so called recentfiles) that represent adjacent or overlapping timespans of file change events.
