darcs repository web UI and hosting app. This is the main darcsden trunk, which also runs hub.darcs.net. (https://hub.darcs.net)

#168darcs hub has no donate button or funding model

I have been encouraged to work on this a bit. I've taken care of the easy part: there is now a paypal button on the front page. Also a little funding blurb, and some project financial stats, based on a full public ledger which we're now keeping.

Next steps: add Patreon and Gratipay buttons; more automated financial reports; continue cultivating community support to increase darcs hub sustainability. Ideas and help welcome.
