+========== How To Upload ==========
+You can upload files to this site via a simple HTTP POST, 
+e.g. using curl:
+curl -F "file=@/path/to/your/file.jpg" $url
+
+Or by choosing a file and clicking "Upload" below:
+
+
+ + + +
+
+(Hint: If you're lucky, your browser may support drag-
+and-drop onto the file selection input.)
+
+
+========== File Sizes etc. ==========
+The maximum allowed file size is $MAX_FILESIZE MB.
+
+Files are kept for a minimum of $MIN_FILEAGE, and a maximum 
+of $MAX_FILEAGE Days.
+
+How long a file is kept, depends on its size. Larger 
+files are deleted earlier than small ones. This relation 
+is non-linear and skewed in favour of small files.
+
+The exact formula for determining the maximum age for 
+a file is:
+
+MIN_AGE + (MAX_AGE - MIN_AGE) * (1-(FILE_SIZE/MAX_AGE))^$DECAY_EXP
