Nginx mass dynamic virtual hosts like apache?

[anagio]

Hello

I'm new to nginx and was wondering if there is a configuration that is
similar to apaches mass dynamic virtual hosts
http://httpd.apache.org/docs/2.0/vhosts/mass.html

I'm having an SaaS developed where users will get a subdomain and would
like to set this up as efficiently as possible. As of now i'm using
apache but would like to move to nginx and get this setup

Thanks
