        SvarDOS stub, or how to plant a SvarDOS seed in a foreign land

        --------------------------------------------------------------

This archive contains files that allow to install a SvarDOS stub within

another DOS system. This makes it possible to use the SvarDOS online repository

of packages on non-SvarDOS systems, assuming you have a network card connected

to the internet and a suitable packet driver.

If you do not have internet connectivity, then you will still be able to

install SvarDOS packages (*.SVP) once you copy them to your PC. You can fetch

SvarDOS packages at <http://svardos.org>.
