Mac OS X contains the utility Migration Assistant,
which can transfer users, application settings,
and various files from an old Macintosh to a new
one. Mango tries to bring similar functionality to
Linux, but with wider OS and application support.
Scout is a command line utility which allows the
users to search in packages using indexes of
various attributes. Each functionality has its own
module. It is accompanied by a small tool which
prints useful messages about packages when a
command is not found in the shell.
