How to create an array or list in a default.conf file
===

I've inherited a python script that is pulling some variables from a default.conf file which I believe is a Machine configuration file.

One of the parts of the script is pulling a configuration key from the .conf file and expecting there to be a list of possible options however right now there is just one option and I'm unsure of how to make it so there are multiple options. 

    [syndication]
    name = Test Name
    title = Test Title
    categories = Category 1

So in the above example the config key is `syndication` and the variable I'm trying to add multiple options to is `category`.

Thanks!
