The MWNightly tool has been down for a while (since February, around migration to Git), so
I took the liberty to write a new tool for this.
https://toolserver.org/~krinkle/mwSnapshots/
Updates hourly, even.
With Git making packages of a repository is a lot easier, but for those without
command-line expertise this is still a comfort.
Source code and issue tracker online as usual (see links in the tool)
