 #
+# Note that it does not make automatic file indexes of directories,
+# and it only shows the files that are there. Some files are handled
+# by their file extension, such as: .avi, .cgi, .css, .gif, .htm,
+# .html, .jpg, .js, .mov, .mp3,.mpg, .pdf, .png, .wav, .zip. Those
+# files are served with appropriate mime types, except .cgi which if
+# executable will be executed as a near CGI 1.1 script. Other files
+# are served with type "text/plain".
