Package blacklist

[CRKatri]

It would be nice if it was possible to set a blacklist of packages that I would not like downloaded/extracted. This new option would accept a comma separated list of packages like -only_render_pkgs except be for packages to skip downloading for, instead of a whitelist of packages to render.

What do you need this for? Either way, should be easy enough to implement. Do you want to send a PR?

Well I wanted to exclude certain packages with conflicting manpages, because there isn't a good way to programatically decide which is a better packages (ie flex vs flex-old). I have a bunch of jank patches to extract the manpages in a format to be parsed by mandoc's man.cgi which won't work well with conflicting manpages.

I was able to implement this by changing https://github.com/Debian/debiman/blob/master/cmd/debiman/getpackages.go#L91 to check a map of strings and bool and if it's in there:

entry = pkgEntry{}
continue

It seemed to work correctly based of some small testing

It would probably be a little cleaner to do the check next to line

debiman/cmd/debiman/getpackages.go

Line 131 in 38831b8
