This is a stand-alone server for Mercurial repositories, that provides
Mercurial data in the form of JSON requests.  This allows for much
more efficient polling of repository data from long-running
applications, such as websites, IDEs, and so on.

For historical reasons--this functionality was originally merely part
of a website--this service requires Django.  There is no reason moving
forward why this need be the case, and no effort should be put into
using Django facilities over hand-rolled ones.
