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.
+
+ If new files fail to be "cvs add"ed, they need to be manually
+ removed from under /path/to/webpages/cvs/checkout before retrying
+ upload-manuals, because if they exist, they will not be handled as
+ "new" files, and will not be "cvs add"ed by the next run of the
+ 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.
