The file I attached was generated upon request - my own one.

My expects full tree, but does no require this from end user.

for example, 'octave' is described this way:

"

- please pay attention to existence of $shadow_targets_hash_refs items.

When the description file is being require'd in Perl, full tree is built.

This is because every target is "registered" in the %shadow_targets_hash_refs.

The file I once attached ("octave_dependencies.prl.gz") is processed and dumped
out full tree.

For a change, but for no good reason (simply didn't have time to transform this
piece of code) 'gtk+' is described this way:

- i.e. a mixture of "flat" and fully hierarchical description.

I emphasize it - it's not that 'gtk+' and/or my tool needs it, it's for 
historical
reasons.

Perl is flexible enough to allow to construct the needed full tree whatever way 
one
likes.
