Urpkg is software to install programs in a safe
and undoable way. It is able to see what files any
given installation command creates, and list and
remove them. You are able to restrict the
installation command so that it only writes where
you allow it to, and does not overwrite files from
other packages. Urpkg is especially useful if you
want to install programs from source, or create
binary packages in an automated way. Under the
hood, urpkg creates a user for each package it has
to install, which prevents the installation
command from run with root privileges. It can be
seen as a "command tracer" that remembers what
files a command created and prevents it from doing
forbidden things. It is written in C but relies on
some external commands, like GNU Find.
