If I understand correctly, you are talking of something similar to the
Debtags::Packages class (Implemented in DebtagsPackages.{h,cc}).  Or you
mean something different?

About the search pattern, I'm a bit wary in mandating user-related
syntaxes, as every implementing program may have his own one...

I understand now.

I've added a new "facet_only" parameter to the
Debtags::Environment::init() function, defaulting to true: if you set it
to false, UnfacetedRemover is not used, and in its place I use a
FacetTagAdder class that adds a facet-only tag for every faceted tag
(for example, use::chatting becomes "use, use::chatting").

I'll commit the change as soon as I get online, and it'll be in the next
version of libdebtags.

Yes... I'd like to get rid of them, though.

As a side question: someone knows about handy ways of integrating
doxygen into an automake build system?


Ciao,
