compat: ask pytype to ignore some warnings
It's expected to have a bunch of import and attribute errors in this module
because it's for compatibility with different versions of hg and Python.
Although it doesn't explain why a function wouldn't have __code__ attribute? So
far I think it's a quirk of pytype.
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.
