+a backup copy is made though. Information is read out of these
+backup copies and restored to the new files by the
+loncaparestoreconfigurations script. To ensure that
+new file permissions and ownerships are installed, a final set of
+chown and chmod commands are called for each of
+the configuration files.

+If you are truly paranoid, you can just make the +Makefile.configinstall file and then save, copy, +and restore all the configuration values yourself. +loncaparestoreconfigurations is pretty smart though, has yet to +fail, and besides, a backup copy is always made (time-stamped so that backup +copies are not overwritten). +

+A BinaryRoot directory is generated that reflects the locations,
+ownerships, permissions, and contents for all the CVS source
+files, compiled binaries, directories, and links as they should eventually

+loncom/build/make_rpm.pl is robust (tested over the +span of months) and, unlike other automated RPM-builders, cleanly +builds new RPMs without any after-effect of temporary files left +on the system. (On the negative side, there are a number of +LON-CAPA specific customizations inside make_rpm.pl which, for +the sake of reusability, should eventually be removed). Two new RPMs +are generated: LON-CAPA-base-3.1-1.i386 and LON-CAPA-setup-3.1-1.i386.rpm +(again, never manually install LON-CAPA-setup-3.1-1.i386.rpm). +
