@sjsrey the whole readme is now lowercase. I assume that was not an intention?

Good catch! No, that wasn't the intention. I will have to see what automated that?

On this, tab completion still works on my end. However, the API is a bit polluted now.

>>> import pysal
>>> dir(pysal)
['__builtins__',
 '__cached__',
 '__doc__',
 '__file__',
 '__loader__',
 '__name__',
 '__package__',
 '__path__',
 '__spec__',
 '__version__',
 'base', # this is new, not in the hierarchy
 'explore',
 'federation_hierarchy', # this is also new
 'lib',
 'memberships', # This is also new
 'model',
 'versions', # this is also new
 'viz']

I'd think versions could be amalgamated into the __version__ attribute, or alternatively __subpackage_versions__, with federation_hierarchy and memberships staying in base. Is this possible?

After a bit more introspection, the tab completion is a little awkward for the layers. It works fine for the packages once they're imported from the layers, but there is a bit of a lag completing on the layer name. In addition it does pollute the namespace so I think we can roll back for now and revisit it after the 2.3 release.

Should this be 'access': 'model',?

[sjsrey]

Yes - good catch!

Replacing this with #1189
