# Update the workshop section of the website
#
# - Trawl the source directories
#
# - If there's a file in the workshop that's also in the source
# directory, and the source directory version is newer, copy it
# over. This allows me full control over what's in the website
# while at the same time keeping it up-to-date
#
# - Also generate an entry on index.html for the file
#
# September 2002:
# Sort the files by filename
# 08/03/2004 Add timestamp to file listing
# 16/11/2004 Woo, google adsense
