autoroutes writes routes for you based on a simpler routing
configuration file called routes.conf. Example:

----- BEGIN routes.conf-------
127.0.0.1   /examples/default
domain1.com /app1/default
domain2.com /app2/default
domain3.com /app3/default
----- END ----------

It maps a domain (the left-hand side) to an app (one app per domain),
and shortens the URLs for the app by removing the listed path prefix. That means:

http://domain1.com/index is mapped to /app1/default/index
http://domain2.com/index is mapped to /app2/default/index

It preserves admin, appadmin, static files, favicon.ico and robots.txt:

http://domain1.com/favicon.ico  /welcome/static/favicon.ico
http://domain1.com/robots.txt   /welcome/static/robots.txt
http://domain1.com/admin/...    /admin/...
http://domain1.com/appadmin/... /app1/appadmin/...
http://domain1.com/static/...   /app1/static/...

and vice-versa.

To use, cp scripts/autoroutes.py routes.py

and either edit the config string below, or set config = "" and edit routes.conf

127.0.0.1   /examples/default
domain1.com /app1/default
