 '''zeroconf support for mercurial repositories
 
 Zeroconf enabled repositories will be announced in a network without
 the need to configure a server or a service. They can be discovered
 without knowing their actual IP address.
 
 To use the zeroconf extension add the following entry to your hgrc
 file:
 
 [extensions]
 hgext.zeroconf =
 
 To allow other people to discover your repository using run "hg serve"
 in your repository.
 
  $ cd test
  $ hg serve
 
 You can discover zeroconf enabled repositories by running "hg paths".
 
  $ hg paths
  zc-test = http://example.com:8000/test
