[gentoo-user] Is equery depends still viable

[Harry Putnam]

With recent changes in portage in the last few mnths, is equery in
general and `equery depends' in particular still reliable?

I use it fairly often still, but do notice I get a lot of null output. So I no 
longer trust it fully. At least it doesn't give false positives - what's in 
the putput really is a valid depend.

Do you know off hand if there are any alternatives?

I realize cryptic answers are the ultimate in cleverness and show
massive sophistication but how is this used to show dependencies to
some specific package.

Maybe a little more detail would keep my little pea brain from smoking
under the load ;)

I realise when you've been debugging for a while you're brain may get a 
bit frazzled, but if you looked at `man emerge` you would find the answer.

In sympathy, here are the relevant parts:

SYNOPSIS
  emerge [options]  [action] [ebuild | tbz2file | file | @set | atom]
...
  atom   An atom describes bounds on a package that you wish to  install.
         See  portage(5)  for  the  details on atom syntax.  For example,
         >=dev-lang/python-2.2.1-r2
...

  --depclean
---
           Use  --depclean  together  with
         --verbose to show reverse dependencies.

Now, I have to leave you with something to do to find the _exact_ syntax 
in your situation :)

Why did you not simply try, you lazy fat SUV owner?
Here, I'll do it for you. But I imagine if this will not spoil you even more.

What is the cryptic part here? The answer tells you anything you need
to know. Plus reading some documentation if you don't understand some
bits is always useful. And if you are frightened of depclean you
should at least know what -p means so this wont damage anything.

Regarding udept, I would really like the idea if someone ore the
original maintainer starts continuing this excellent tool. For now it
works quite reliable but being unmaintained I fear it will get more
and more unusable.

dep from app-portage/udept just got recommended to me, but I don't know 
it's trustworthiness either.

qdepends -Q pkgname

qdepends is part of portage-utils.
