# Create forward link pages for relocating a web site.
# Generates one page for every existing site file;
# upload the generated files to your old web site.
# Performance note: the first 2 string.replace calls
# could be moved out of the for loop, but this runs 
# in < 1 second on my Win98 machine for 150 site files.
# Lib note: the os.listdir call can be replaced with:
# sitefiles = glob.glob(sitefilesdir + os.sep + '*') 
# but then the file/directory names must be split
# with: dirname, filename = os.path.split(sitefile);
