Yeah, I've already played with this one.  The 'ForEachLineIn' seems like a
good fit but the 'ReplaceLinesMatchingField' doesn't.  There's really not
one particular field that I can search for in order to replace a line; I
also need to be able to add an entire line if it does not already exist.

I tried using other expressions with 'ForEachLineIn', but it doesn't look
like any work inside the loop except for 'ReplaceLinesMatchingField'.
