packages are easily identified with a *** and local-only packages are also
listed.
pactree - generate a dependency tree of an installed package in textual or
graphical form (using graphviz).
bacman - regenerate a pacman package based on installed files and the pacman
database entries. Useful for reuse, or possible config file extension.
