In message <address@hidden>you write:
>LocateLineMatching "*hey there buddy:*"
>CommentNLines "2"
>which gives the error:

I'm guessing your problem is with the regex.  It looks like you're
trying to use globs instead of regexes.  In order to match that string,
you'll want something like this:

LocateLineMatching ".*hey there buddy:.*"
CommentNLines "2"

In regex-speak, "." means "match any character" and "*" means "match
zero or more of the previous character".  Basically, regex ".*" is
eqivilant to glob "*".

If there's a chance that those lines might not be in the file at all,
you'll want to wrap a "BeginGroupIfLineMatching '.*hey there buddy:.*'"
"EndGroup" around those lines above.  "LocateLineMatching" will abort
editing of the file if no match is found.
