+; Tox is a testing tool that manages virtualenvs for testing multiple Python
+; environments in a consistent/controlled way.
+
+; SETTING ENVIRONMENT VARIABLES AND TOX TESTING VARIABLES
+;
+; You can limit tox testing to certain environments via the `-e` (envlist)
+; command line option:
+;    tox -e py27-core,py34-core
+; OR, you can just set the `TOXENV` environment variable, which is handy:
+;    TOXENV=py27-core,py34-core
+;
+; Integrating with the virtualenvs in Circle CI is a bit of a pain. For
+; whatever reason the "executable" `python35` (at the time of writing) cannot
+; be activated directly. Instead the circle.yml file specifies the actual
+; binary directly. Because of this, you too have to set the following env
+; variables:
+;    PLOTLY_TOX_PYTHON_27=python2.7
+;    PLOTLY_TOX_PYTHON_34=python3.4
+;    ...
+; These will be specific to your machine and may not look like the ones above.
+; If you're not testing with all the python versions (see TOXENV above),
+; there's no need to install and map other versions.
+
+; PASSING ADDITONAL ARGUMENTS TO TEST COMMANDS
+; The {posargs} is tox-specific and passes in any command line args after `--`.
+; For example, given the testing command in *this* file:
+;   nosetests {posargs} -x plotly/tests/test_core
+;
+; The following command:
+;   tox -- -a '!slow'
+;
+; Tells tox to call:
+;   nosetests -a '!slow' -x plotly/tests/test_core
+;
+; Which is a nice way to skip slow tests for faster testing cycles.
+
+[tox]
+; The py{A,B,C}-{X,Y} generates a matrix of envs:
+;   pyA-X,pyA-Y,pyB-X,pyB-Y,pyC-X,pyC-Y
+envlist = py{27,34,35}-{core,optional}
+
+; Note that envs can be targeted by deps using the <target>: dep syntax.
+; Only one dep is allowed per line as of the time of writing. The <target>
+; can be a `-` (hyphen) concatenated string of the environments to target
+; with the given dep.
+
+; These commands are general and will be run for *all* environments.
