Re: gopher directory listing script

[Toni Ruottu <toni.ruottu () iki fi>]

It is possible to show a url for each file/dir.
0About This Server      /About This Server.txt  gopher.quux.org 70      +
...translates to...
gopher://gopher.quux.org:70/0/About%20This%20Server.txt

I though that displaying a full url for each entry would be too much,
and decided then to hide even the filenames. What do you think. Should
I show the full urls or what? Maxlines makes sense to protect against
large (not to mention infinite) gopher listings. I might also add an
option for recursing into directories.
