The Rotate directive allows you to define an unlimited number of rotating
messages or image specifications that reside in files. It is called by the
[rotate] tag. If the file does not exist at program configuration time, the
tag is simply stripped. The line in the catalog.cfg
file takes the form of the directive, followed by any number of vend-style
file names (relative to the PageDir, with no .html suffix).
