[Swift-devel] ssh data provider

[Zhao Zhang]

Hi, Mihael

If I put .passphrase= there, I got this:
zzhang at login6.surveyor:~/swift/test> swift -sites.file ./sites.xml 
-tc.file ./tc.data first.swift
Swift svn swift-r2334 (Swift modified locally) cog-r2216

RunID: 20081211-1603-qsfmaeif
Progress:
