# Edit the email address in the script below to use your own. The address is
# used as password for anonymous ftp login.
# Should work with any unix ftp client, but uses ncftp prior to the standard
# one.
# If the original ftp client is used, it preserves the original .netrc (if any)
# (NOTE: some shells don't allow the HOME env to be changed this easily
# which will make this script use the ~/.netrc file. If you run a regular ftp
# client that exepects that file while using this script, there might become
# a conflict.)

# USAGE:
#    fileget <site> <remote file> <local file> <temporary download name>
