py3: return unicode from setup.py's get_version
py3 expects the version number for eggs to be unicode, so despite 9.2.0 being
the first evolve release with beta py3 support it isn't currently pip
installable since it dies with:
File "*/setuptools/command/egg_info.py", line *, in tagged_version
return safe_version(version + self.vtags)
TypeError: can't concat str to bytes
The `setup.py install` test added in a previous commit should cover this since
it died in a different but similar way before.
Doc is generated with sphinx.
You can generate the doc with:
```
make
```
# Tutorials
For updating the tutorials, you need to have the docgraph extension installed
(https://pypi.python.org/pypi/hg-docgraph).
Then run the test-topic-tutorial.t and test-tutorial.t to update the output if
needed.
You'll need the dot binary (likely installed by the graphviz package in your
package manager) in order to have graphviz graphs rendered in the html output.
Simply run make in the docs directory should takes care of the conversion of
the tutorial .t files into .rst files. Then sphinx should do the rest of the
jobs by rendering graphviz graphs.
