I frequently find myself wanting to run hgweb in a production-like
environment, with a real HTTP server and multiple WSGI workers.
This patch introduces a Docker environment for running Mercurial
under Apache + mod_wsgi. With just a few command executions, it is
possible to spin up a Docker container running hgweb.
The container is tailored for Mercurial developers wanting to run
Mercurial from a source checkout. It is **not** meant to be something
suitable for production use.
The container provides a default hgweb environment with an empty
repository that allows pushes. You can thus start a container and push
your favorite repository there for quick testing.
The container is designed to allow customizations. Users can provide
their own hgweb configurations and mount existing directories containing
repositories into the container.
The behavior of the container and how to control things is documented in
the README.rst file.
