#usage: $1 is the directory to be served over gopher.
# If a file is executable it is going to be used as a program.
# If there's a .header file in any directory it'll get printed
# before the directory listing.
# gopherd.sh tries to guess the hostname to use for people accessing the
# server (since there isn't a header for it like in HTTP).
# this requires rDNS records to be set correctly.
# Or you can just comment out that code and put a value at
# "export hostname" down there.
