SliTaz has a built in package convertor that allows you to convert *.rpms and *.deb packages to install.
You will manually need to install any dependencies, so check the package source for any dependencies.
Open the terminal and type the following, you will have to be in the same directory as the rpm or deb package you are wanting to convert unless you enter the full path
tazpkg convert thepackage.rpm
tazpkg convert thepackage.deb
The completed tazpkg will be output in the same directory as the rpm or deb package
