Here’ a nice articile about smartpm :
a teaser :
but what Smart’s supporters claim sets it apart is its package selection algorithms. Installing or upgrading packages is not always a simple task, and it is not uncommon for Debian’s APT or Fedora’s yum to err in their attempts, causing broken packages or unmet dependencies. While Smart is not infallible, it is designed to overcome such issues and deliver to users the best possible systems, even if the most obvious route cannot be taken.
Smartpm was discussed at the Ubuntu Developers Summit in paris. See :
Smartpm might be available in Edgy as an alternative package manager (which can live next to apt). One thing to note is that it is not adviced to use smartpm to add non-apt repositories (I heard this at the spartpm BOF).
I’ve started a thread about “Smart Package Manager”.
