“Many application files are available as both as deb packges as
well as in .rpm format s but sometimes we may find that the
aplication that we need to install is in amother format than what
we actually need. So the only plausible way to install it would be
to convert one package format to another.Before starting the conversion we need to install ALIEN which
helps us to do the conversion. FYI Alien is a program that converts
the rpm, dpkg, stampede slp, and slackware tgz file formats into
each other.
