mercurial server multiple repositories

Serving multiple repositories using hg serve.

Here's my hgweb.config file:

[paths] 
project-a = C:/hg/project-a/ 
library-b = C:/hg/library-b/ 

I start hg serve with this command:

hg serve --address 127.0.0.1 --port 8000 --webdir-conf C:/hg/hgweb.config --encoding utf8
