pt-stalk removes user's files from the destination directory

[ding]

I find a problem in use,my command
"pt-stalk --user=pt --host=10.3.138.109 --port=3310 --password=ptpasswd --sleep=10 --threshold=0 --iterations=24 --daemonize --dest /web"
when it is executed i find my some files in /web disapaered. The tool delete some files in /web In a violent way. But the doc dose not stament this clearly . I only find some description about --retention-time .

--retention-time
type: int; default: 30

Number of days to retain collected samples. Any samples that are older will be purged.
This says the samples will be purged not all files. This description Makes one confusion easy.
So i have some suggestion about this: 1.stament the risk in some obviously place.2.delete specify file not all.
