Urubu version 0.8 and higher

The urubu serve command takes the baseurl setting automatically into account.

Urubu version 0.7

The urubu serve server does not include the baseurl prefix when serving pages so sites that use baseurl can't be previewed locally using urubu serve. An alternative option is to use tservice, which includes an option to serve a local static site with a URL prefix. To use tservice with an Urubu site instead of using urubu serve call tserve with the prefix option, e.g.

tserve --prefix <baseurl> _build

Where <baseurl> is your site's particular prefix.
