The various words each have a numerical value.  What you try to do with a
UUCP map is get a numerical value appropriate to your site... to that
purpose, you can also combine them, do get things like DAILY+LOW.  I am
doing this from memory, believe I read it in the news.announce hierarchy
someplace... but DAILY and POLLED have the same value, around 3000 I think,
and DAILY is supposed to mean you call them, POLLED means they call you.
The lower the number, the better the link, so if you do a DAILY+LOW that
means it's a low-quality link and should be routed around.  HIGH is
actually a negative number (HIGH and LOW are +5 and -5 respectively).
You can multiply or divide, for instance DAILY/2 means twice daily, and
should give you 1500 if I remember correctly.  It isn't super-important
that all the words be right, as long as the numbers are roughly appropriate
to the quality of the link.

If you want more info on this, talk to Bob Leffler or Kevin Darcy, I'm sure
they know more than I do about it.

It's all in the pathalias(8) man page, available at your favorite
pathalias archive site, like citi.umich.edu:pub/honey/pathalias/pathalias.Z

          LOCAL       25   (local-area network connection)
          DEDICATED   95   (high speed dedicated link)
          DIRECT     200   (toll-free call)
          DEMAND     300   (long-distance call)
          HOURLY     500   (hourly poll)
          EVENING   1800   (time restricted call)
          DAILY     5000   (daily poll, also called POLLED)
          WEEKLY   30000   (irregular poll)

     In addition, DEAD is a very large number (effectively infin-
     ite), HIGH and LOW are -5 and +5 respectively, for baud-rate
     or quality bonuses/penalties, and FAST is -80, for adjusting
     costs  of  links  that  use  high-speed  (9.6 Kbaud or more)
     modems.  These symbolic costs represent an imperfect measure
     of  bandwidth,  monetary cost, and frequency of connections.
     For most mail traffic,  it  is  important  to  minimize  the
     number  of hosts in a route, thus, e.g., HOURLY * 24 is much
     larger than DAILY. If no cost is given, a default of 4000 is
     used.

From pathalias's parse.y file:

	{"DIRECT", 200},
        {"DEMAND", 300},
        {"DAILY", 5000},
        {"HOURLY", 500},
        {"DEDICATED", 100},
        {"EVENING", 2000},
        {"LOCAL", 25},
        {"LOW", 5},     /* baud rate, quality penalty */
        {"DEAD", MILLION},
        {"POLLED", 5000},
        {"WEEKLY", 30000},
        {"HIGH", -5},   /* baud rate, quality bonus */
        {"FAST", -80},  /* high speed (>= 9.6 kbps) modem */
        /* deprecated */
        {"ARPA", 100},
        {"DIALED", 300},

Also, if a cost is omitted, e.g.

foo	bar

then it's assigned a default value. In my pathalias version, this default 
value is 4000, putting it somewhere between EVENING and DAILY. I'm sure this
comes as a shock to the many folks who apparently think the above syntax is 
equivalent to declaring an alias, which has an effective cost of 0, i.e.

foo = 	bar

There are some fairly good README files and man pages on this stuff, if I 
recall, but if those prove insufficient, talk to Peter Honeyman. I'm sure he 
knows more than I do about it. :-)

Dat's what I needed Ed, thanks for taking the time to post something that
I had online in my man pages. ;) OK, I guess the systems locally here in A2
that call destroyer could be considered toll free (DIRECT) I guess I need
to check my own listing, then. ;)
