**NOTE: DO NOT USE RPMs IN SLACKWARE!**
It is *not* advisable to install RPMs in Slackware, since it is not an RPM based distribution, and there is no easy way of managing them. Instead, you should really try to get packages for Slackware in its native *.tgz format (a gzipped tar file, containing the binaries instead of source code, which is installed as root with the command 'installpkg myprogram.tgz'.) If you must use RPMs, the command 'rpm2tgz myfile.rpm' will convert the rpm to a tgz package. You will likely have to get used to compiling from source with Slackware, as many programs do not always offer a Slackware package (but
LinuxPackages may have one).
RPM's can be installed as they are using 'rpm -i thefile.rpm', but this is really not recommended.
