"nxFileLine: ensure that a file contains a specific line and/or does not contain lines matching a given pattern."
Like grep? They've replicated a very small part of grep as new software for only their environment? They just don't get 'tools', do they?
Note how they say it "manage lines" - it doesn't. It just greps a file. Is this grandiosity or ignorance, I never can tell with MS...
