stack new: What is the purpose of "category" and "copyright" params for templates.

[Simeon Filipov]

Recently I noticed that when I'm creating a project using "stack new", I am asked to provide 5 parameters for the template. These can either be passed to the stack new command using -p/--params or by putting them in $HOME/.stack/config.yaml. The purpose of 3 of these is obvious:

• author-email
• author-name
• github-username

The other two I am not sure about: 

• category
• copyright

 What part of the project generation do they affect?

Lastly, there is no mention of these in https://github.com/commercialhaskell/stack/blob/master/doc/yaml_configuration.md. Where is the right place to document these?

I found the answer myself - both of these go inside the cabal file. More information about them can be found here: https://www.haskell.org/cabal/users-guide/developing-packages.html#package-properties

Should these be mentioned somewhere in stack's documentation for people not familiar with cabal?
