Writing to pyproject.toml file so that it processes correctly on pypi

[pkopparla]

Hello,

I was having a wonderful time with maturin writing python bindings for a rust library, till I hit the publication part.
I'm trying to figure out how to write my pyproject.toml file so that pypi shows the correct homepage url, license and other things. It has been incredibly frustrating since there's no examples and the error messages are somewhat vague. For instance, I want my github homepage url to show up on the pypi package page, I've tried both url = "https://github.com/zonebuilders/zonebuilder-py" and homepage="https://github.com/zonebuilders/zonebuilder-py", the distribution build works with either but the homepage link doesn't show up in pypi. I think the key needs to be something like project-url with some two value array going by the PEP 621 page here: https://www.python.org/dev/peps/pep-0621/#urls

Similar for the license. I can get it to build with license_file=LICENCSE, but it doesn't show up on pypi. I've tried many variations with the license keyword, eg. license = ["file", "LICENCE"], license = ["file = LICENCE"], license = ["file" : "LICENCE"] etc etc and I'm about to lose my mind. How does one figure out the right way to do this? Why are the references are so complicated?

There is an example in PEP 621: https://www.python.org/dev/peps/pep-0621/#example

You can also just specify homepage and license in Cargo.toml, maturin will use it automatically.

Copied the PEP 621 example to user guide so it's easier to find: https://maturin.rs/metadata.html
