Distribution subclass that supports bdist_conda options

This class is required if you want to pass any bdist_conda specific

options to setup(). To use, set distclass=CondaDistribution in setup().

**NOTE**: If you use setuptools, you must import setuptools before

importing distutils.commands.bdist_conda.

Options that can be passed to setup() (must include

distclass=CondaDistribution):

- conda_buildnum: The build number. Defaults to 0. Can be overridden on

the command line with the --buildnum flag.

- conda_buildstr: The build string. Default is generated automatically

from the Python version, NumPy version if relevant, and the build

number, like py34_0.

- conda_import_tests: Whether to automatically run import tests. The

default is True, which runs import tests for the all the modules in

"packages". Also allowed are False, which runs no tests, or a list of

module names to be tested on import.

- conda_command_tests: Command line tests to run. Default is True, which

runs ``command --help`` for each ``command`` in the console_scripts and

gui_scripts entry_points. Also allowed are False, which doesn't run any

command tests, or a list of command tests to run.

- conda_binary_relocation: Whether binary files should be made relocatable

(using install_name_tool on OS X or patchelf on Linux). The default is

True. See the "making packages relocatable" section in the conda build

documentation for more information on this.

- conda_preserve_egg_dir: Whether to preserve the egg directory as

installed by setuptools. The default is True if the package depends on

setuptools or has a setuptools entry_points other than console_scripts

and gui_scripts.

- conda_features: List of features for the package. See the features

section of the conda build documentation for more information about

features in conda.

- conda_track_features: List of features that this package should track

(enable when installed). See the features section of the conda build

documentation for more information about features in conda.

Command line options:

--buildnum: Set the build number. Defaults to the conda_buildnum passed to

setup(), or 0. Overrides any conda_buildnum passed to setup().
