dak is the collection of programs used to maintain the Debian project's archives. It is highly optimized for the Debian project, though can be used by others too.
There are some manual pages and READMEs in the docs sub-directory. The TODO file is an incomplete list of things needing to be done.
There's a mailing list for discussion, development of and help with dak. See:
https://lists.debian.org/debian-dak/
for archives and details on how to subscribe.
We love to get patches for dak. Enhancements, bugfixes, make-code-nicer/easier, anything.
With dak being available at the Salsa Service, we now prefer receiving merge requests there. They allow simple reviews using the webinterface and also allow discussing (parts of) the code within the Salsa UI. They also allow much easier tracking the state of different requests than a mail on a list ever allows.
To create merge requests that, simply go to the Salsa project page, select Fork followed by the namespace you want to put it in (usually your private one). Then simply clone this fork and work it in, preferably in a branch named after whatever-you-are-doing.
When you are happy with what you coded, use the UI on Salsa to create a merge request from your feature branch, either using the web interface or by using e-mail, see the Gitlab MR documentation for details on this process.
While we do prefer merge requests as described above, we also accept patches send by mail to our mailing list, see above for details on the list.
You can find more info about setting dak up inside the setup Folder and its README.
