Bug#301041: apt-cache: dependency graph for build dependencies



Package: apt
Version: 0.5.28.6
Severity: wishlist

"dotty" command of apt-cache is really useful, but works only for binary
packages. I had the need of generating graphs of build dependencies in
order to decide the proper order of uploading packages to avoid
autobuilder fails for unmet build dependencies.

I wrote a script which is able to generate such graph using
libapt-pkg-perl. It is available here:

  http://svn.debian.org/wsvn/pkg-ocaml-maint/tools/build-dep-graph/build-dep-graph.pl?op=file&rev=0&sc=0

Sample output is here:

  http://svn.debian.org/wsvn/pkg-ocaml-maint/tools/build-dep-graph/ocaml_build_deps.png?op=file&rev=0&sc=0

Still, the proper place for such a feature seems to be apt-cache itself,
is it possible to add it?

Thanks in advance,
Cheers.
