   If upload-manuals fails, resolve the problems and re-invoke it.
   This requires running make-manuals again, since upload-manuals
   destructively modifies the 'manual' directory where you invoke it.

+  removed from under /path/to/webpages/cvs/checkout before retrying
+  upload-manuals, because if they exist, they will not be handled as

+  script.

   Also, upload-manuals invokes "cvs commit -f", so if you run it
   several times, some files will be committed more than once even
   though they were not changed in-between.  Suck it up.
