UUCP Processing Order

Apparently, it was yet another RTFM question, so I apologize.
I have received a few responses, all of them pointing me the the '-g'
(grade) flag in the 'uucp' and 'uux' commands. Tim Evans supplied the most
detailed response and also dealt with the 'uusched' question.
tim> uusched randomizes the order of the remote *systems* it contacts, not
tim> the jobs. If you have more than one UUCP link and have jobs
tim> scheduled for each at every run of uusched, the order in which
tim> systems are contacted is randomized, but not the order of the
tim> jobs themselves.

tim> The order of the jobs themselves is controlled by the UUCP
tim> "grading" scheme. See the UUCP chapter of the System and
tim> Network Admin manual, under the "Systems File" heading, "Grade"
tim> subheading. I believe you can change the default grade for
tim> mail in your sendmail.cf file's "UUCP Mailer Specification"
tim> section by adding the 'g' argument to the uux command line;
tim> see the uux man page.
