# ForceType 'text/plain; charset=UTF-8'
# </FilesMatch>

# To set up in mathopd, configure like this:
# Control {
# Alias /samples
# Location /home/userID/gradint/samples/
# AutoIndexCommand /home/userID/path/to/samples.cgi
# }
# and delete the REQUEST_URI logic below.
# You can override this script in selected (sub)directories
# by making index.html files for those.
