                     85: <li>Be careful about installing a LON-CAPA-mysql RPM.  You need to run

                    106: RPMs which should maybe be upgraded.  Important specification
                    107: files for RPM installation are CVS:doc/otherfiles/rpm_list.txt

                    116: For example, to upgrade your LON-CAPA-systemperl RPM, you
                    117: would enter commands like
                    118: <blockquote>

                    124: <b>Remove RPMs which do not belong:</b>
                    125: If an RPM should NOT be on your system (like apmd), then you want
                    126: to remove this RPM.  Since RedHat is a little erroneous when
                    127: it comes to dependencies, you may wish to use the --nodeps flag.
                    128: <blockquote>
