New 'maint' facet for Debtags

[Moritz Muehlenhoff]

Hi Enrico,
I'm currently in the process of setting up a test installation and I already
have an initial question:
Is there a mechanism which derives tags from other regular package meta
data automatically?

IOW, can the tags for "no security support" be automatically derived from every
package being non-free or contrib or would this require a script, which monitors
package changes?

Cheers,
        Moritz
