+    This script handles various "fixup transitions" that might need to 
+    occur to help existing sites smoothly upgrade to newer releases of 
+    PmWiki.  Rather than put the workarounds in the main code files, we 
+    try to centralize them here so we can see what's deprecated and a
+    simple switch ($EnableTransitions=0, or ?trans=0 in the url) can tell 
+    the admin if his site is relying on an outdated feature or
+    way of doing things.

+## However, some sites and skins have customized $PageEditFmt -- if
+## that appears to have happened we restore PmWiki's older defaults here.
+## If not, then we take any $EditMessages (which may have come from
+## cookbook scripts) and stick them into the new $MessagesFmt array.
