# Description:  Keep a simple text-based logger for the Trawler
#               Now used as a general purpose error logger.
#
# Date          Change
# -----------------------------------------------------------------------------
# 20/02/2003    Needed much better logging to see what was going on in the Trawler
#               especially for Collections
# 01/05/2003    Write to a text log
# 01/07/2004    Small change for logging searches, and form submission
#               used in development to see what's going on
# 21/08/2005    Added a proper die - if logfile could not be opened
# 23/08/2005    N.B. The error log file must have permissions set so that all
#               users can append to it!
