Note: you don’t have to close/reopen-new-PR every time you make a change to it. Just push a new commit to your branch, and GitHub will automatically update the pull request.

Also, could you, please, edit the description of this pull request and describe exactly what is the goal of this pull request, what is being changed, and which issues are resolved by it? It is crazy that we have to disassemble your intent by deciphering your code and trying to divine your intent from it.

Thank you for your effort!

i'm too lazy for giving description of the pull request, and the goal was simply make tool works as it should, because at the current state tool is buggy, for example, the Maintainer field is empty when generating sources for Debian, or, some tags on RPM based sources, generated by tool, contains multiple lines

Right, so I was trying to be nice. Next time, there will be PR without description and reference to the ticket describing the issue such PR solves, it will be closed without reading.
