stupid cfenginequestion

[Steffen Grunewald]

Hi,

I'm trying to configure cfengine to do a bit more than before, and now
I need to replace a string within a line.
I can skip forward to the line containing old_string by
	LocateLineMatching "old_string"
and could do 
	CommentNLines "1"
	Append "line containing new_string"
but I don't want to rely on the contents of the line, except "old_string".
Unfortunately, I'm still fighting my weekly Friday blindness, and cannot
find a "Replace" command which would only modify the current line...
Any ideas?

Cheers,
 Steffen
