"""
This allows the user to create a file "timestamps" in their datadir,
that will override the timestamp of any given blog entry. Each line
in this file should be of the form "YYYY-MM-DD-hh-mm file-name".
Then for any entry that one of these lines exist the system will use
that timestamp instead of the actual files modification time.
 
Note: the filename is relative to your data-dir.
Example of a line for the file /var/data-dir/school/abc.txt
   where the datadir is "/var/data-dir/" and the date is Aug 9, 2004.
 
2004-08-09-00-00 school/abc.txt
