Its really simple, and first off, let me say I am not doing rerouting.

What I do is that the path I was given, say a!b!c!d!e!f and start
looking for a match in a file I call rpaths.  I look for longest
match starting with the full path less the final user name.
I keep looking for an exact match stripping off the right most
site until the string is empty, or I get a match.

If I get a match, I turn the address into uucp-remainder (stuff I stripped
off on the right) @ site.

Thus if rpaths contained
a!b!c!d:site.domain

it would be

e!f@site.domain
and then I route that as normal.

Rpaths is made using a simple shell and perl script from the maps.
I grep the maps for the = lines, deleting all comment info and getting
just the first site on the line for those that list many, or the first
site in a row for those that take multiple lines for it.  And then
look up using pathalias the path to get there, sort those, delete my
neighbors I want to use uucp for, and store it in a file as path:site.
