[mew-int 01080] Re: Using GREP to Search Subfolders

[Charles Muller]

Dave,

Thanks for all the suggestions. I'll try a few things and see what
works. I tried Namazu when I first got started in Linux (about six
months ago), and it was too
complicated for me, but perhaps it's time for me to take another shot at
it.
