Software
--------

poliastro wouldn't be possible without the tremendous, often unpaid and
unrecognised effort of thousands of volunteers who devote a significant
part of their lives to provide the best software money can buy, for free.
This is a list of direct poliastro dependencies with a citeable resource,
which doesn't account for the fact that I have used and enjoyed free
(as in freedom) operative systems, compilers, text editors, IDEs and browsers
for my whole academic life.
